Quick Start: A Complete Usage Example

Scenario: Batch Generate Employee Welcome Letters

Let's say you need to generate personalized welcome letters for 50 new employees. Here's how to use Sheet-to-Doc Skill to complete this task.

Step 1: Prepare the Word Template

Create a Word document with placeholders that need to be filled with data:

Dear {name},

Welcome to {company}. Your position is {position}.

Your contact information:
- Email: {email}
- Phone: {phone}

Your start date is {start_date}. Please bring the required documents to the HR department on that day.

We look forward to working with you!

Best regards,
{company}

Save this document as welcome_letter.docx.

Step 2: Prepare Employee Data

Create a JSON file containing all employee information:

{
  "name": "John Doe",
  "company": "Example Tech Co., Ltd.",
  "position": "Senior Software Engineer",
  "email": "john.doe@example.com",
  "phone": "+86 13800138000",
  "start_date": "August 1, 2026"
}

Save as employee_data.json.

Step 3: Let AI Generate the Document

Now, you only need to tell the AI:

"Please replace the data in the template welcome_letter.docx with the content from employee_data.json, and generate a new Word document welcome_letter_output.docx."

The AI will automatically execute the following steps:

Read the Word template
Read the JSON data
Fill the template with the data
Generate the new Word document

Command Line Method

If you prefer using the command line, you can run:

# Basic usage
node scripts/generate.js \
  --template welcome_letter.docx \
  --data employee_data.json \
  --output welcome_letter_output.docx

# Using short parameters
node scripts/generate.js -t welcome_letter.docx -d employee_data.json -o welcome_letter_output.docx

# Using JSON string directly
node scripts/generate.js -t template.docx -d '{"name":"John Doe","company":"Example Tech"}' -o output.docx

The Photos I Almost Forgot: How I Found My Way on a Map

WTSolutions — Mon, 20 Jul 2026 07:09:53 +0000

The Map Hiding in My Photo Album

My phone has nearly 10,000 photos—most of them from trips over the years. But honestly, they just sit there quietly in folders. I scroll through them occasionally, take a look, and move on.

The moment that made me start thinking about this was last year, when a friend asked: "What good photos did you take in Kyoto during your last trip to Japan?"

I searched for a while and only found a few blurry screenshots. With so many photos, I couldn't even remember where I shot them or what I captured. In that moment, I suddenly realized—these photos recorded more than just images. They held time, place, and stories. But all of that information was scattered in the corners of my photo album, never opened again.

An Accidental Discovery

About six months ago, I was searching online for "photo geotagging tools," wondering if there was any way to connect photos with maps. That's when I came across this tool: WTSolutions' Images to Google Earth/Ovi Maps.

Honestly, I didn't pay much attention at first. This kind of tool sounded like something only GIS professionals would use. But when I saw "online version, no download, just drag and drop," I decided to click through anyway.

Drag and Drop—That's It?

The page was remarkably simple. Nothing complicated. I grabbed 6 photos from my Xi'an trip and dragged them onto the page. Then it just started processing automatically.

A few seconds later, there was a download link for a KMZ file on the page.

I was stunned. That was it? No sign-up, no payment, no tedious settings?

Still skeptical, I dragged the KMZ file into Google Earth.

Then I saw something I'd never seen before—those photos appeared one by one on the map, right where I had taken them back then. I could fly over the Earth and click each photo to see the view from that moment.

It's hard to describe that feeling. It was like suddenly having a photo album that could talk.

Ovi Maps: Better for China

Later, I tried again with Ovi Maps. Honestly, Google Earth isn't always convenient in China, and Ovi Maps worked much better for me when I needed to check maps in work scenarios.

In Ovi Maps, the photos appear as icons on the map, and you can click to see the actual photo. For colleagues who need to locate shooting sites for work, this feature is simply a game-changer.

Privacy: What Really Won Me Over

To be honest, I was initially hesitant about online tools. Uploading my personal photos to some unknown website? That gave me pause.

But after reading the website's explanation, I discovered that all processing happens locally in the browser. The photos never get uploaded to any server. This meant—even my most private photos could be handled with confidence.

This was the point that changed my mind entirely. So many online tools require uploading data. The fact that this one processes everything locally is genuinely different.

It Changed How I Organize My Photos

Now, every time I return from a trip, the first thing I do isn't post on social media—it's import those photos onto a map.

Looking at the dense cluster of markers on the map, I suddenly realized—I've been to far more places than I thought. All those "been there" moments, connected on a map, form a real travel trajectory.

And this approach made me re-examine what a photo really means. It's not just a static image anymore—it's a coordinate, a moment, an anchor of memory in space.

Not Just Travel—It's Life

Later, I started using this tool for everyday work too. On one project trip, I took lots of site photos. After importing them into Ovi Maps, the entire project progress became visible at a glance. My colleagues all said, "This feature is incredibly practical."

I also use it for urban exploration. I walk around and shoot photos on weekends, then import them into the map on Sunday night to see where I've been that week. Unknowingly, a "life map" of my own is forming.

Is the Free Version Enough?

For everyday users, the free version's limit of 6 photos per batch is more than sufficient. Most of the time, I don't need to process dozens or hundreds at once, so the free version has been with me all along.

Of course, if you're a power user, upgrading to the Pro version is a reasonable choice. Unlimited processing, custom image sizes, GeoJSON export—these features genuinely solve real problems.

But honestly, as someone who uses this feature occasionally, the free version has already brought me tremendous value.

Wrapping Up

Sometimes I think the value of a tech product isn't about how powerful its features are, but whether it can truly enter our lives and change how we see the world.

For me, this tool is exactly that kind of existence. It didn't teach me any advanced GIS systems, and it didn't make me a photography master. It just helped me rediscover every photo in my album—they're not just images; they're my footprints on this planet.

If you have thousands of photos sitting in your album with no idea what they hold, give this method a try.

You won't just see a map. You'll see the roads you've walked.

I Shot Hundreds of Drone Photos—Here's How I Turned Them into a Flight Path

WTSolutions — Mon, 20 Jul 2026 07:08:37 +0000

Hundreds of Photos, One Folder

I'm a drone enthusiast—not professional, but someone who loves taking their drone on every trip. Honestly, the best part of drone flying isn't the shooting moment itself, but the review. That bird's-eye perspective is something only someone who's actually flown a place can truly understand.

But after every flight, hundreds of photos get dumped into a folder and just pile up. I'll open a few occasionally, but they quickly get buried under the next batch.

It wasn't until one day that I realized—these photos aren't just images. They're a flight trajectory.

From One Photo to an Entire Map

Every time I fly, the drone automatically records GPS data for each photo. Theoretically, if I could extract that GPS information and place the photos back on a map, I could see exactly where my drone flew.

But doing it manually? Hundreds of photos, opening each one's properties, copying coordinates, pasting them one by one into a map—just the thought of it made me give up.

That was until I found WTSolutions' Images to Google Earth/Ovi Maps.

Drag and Drop—It Just Gets It

The operation was so simple it almost embarrassed me. I dragged an entire folder of photos onto the webpage, and the tool automatically extracted the GPS data from each image. Within seconds, it generated a KMZ file.

I downloaded it, dragged it into Google Earth.

Then I saw something I'd never seen before—every photo my drone took appeared one by one on the map, connected in flight order into a continuous path. I could see the entire flight area at a glance, and clearly understand the spatial relationship between every shooting point.

It's hard to describe. It was like I finally had a real map of my entire flight.

This Is Almost a Must-Have for Drone Operators

Honestly, as a drone operator, this tool solved a problem I'd always wanted to solve but never imagined could be this simple.

Flight debriefing. After every flight, I can clearly see which areas I covered, how far I flew, and which spots I missed. This has helped me improve my flight technique significantly.

Client delivery. Sometimes I do aerial work for others—construction sites, terrain surveys. I just send the KMZ file to the client, and they can open it in Google Earth to see exactly where each photo was taken. No more explaining photo by photo "where is this?"

Creative inspiration. Sometimes after a flight I realize I missed an angle. But looking at the map, I can figure out that flying from another direction would fill the gap. The map gives me a much better sense of spatial relationships in my flights.

Ovi Maps: A Drone Enthusiast's New Favorite Tool

For drone operators in China, Ovi Maps is actually more practical than Google Earth.

The reason is simple: Ovi Maps can overlay various layers—contour lines, satellite imagery, terrain maps. After importing the KMZ file, I can see photo positions in the actual flight environment, combined with contour lines to judge altitude and terrain relationships.

Once I was flying in a mountainous area. After importing the photos into Ovi Maps, the contour lines revealed a valley I had completely missed. I later flew specifically there and captured some stunning shots I never would have found otherwise.

A Special Request: Helping a Village Map Its Collective Assets

What truly made me realize this tool's value extends far beyond personal interest was a special request from a client.

One day, a friend who does drone aerial photography reached out. He was working on a survey for a village—mapping their "san zi," the collective assets of rural communities: funds, physical assets, and natural resources like land, forests, water bodies, and buildings that belong to the entire village.

For years, these assets were recorded on paper ledgers and kept in the memory of aging village officials. Boundaries were unclear, areas didn't match, and the accounts were a mess. Now policy demands digitalization—every plot of land, every forest patch, needs to be mapped precisely.

"I flew dozens of missions and took over a thousand photos," he told me. "But photos alone aren't enough. I need to turn the GPS location of each photo into a manageable map."

I had him try this tool. He dragged the GPS-tagged drone photos into it, generated a KMZ file, and imported it into Ovi Maps.

Then I saw what delighted him—every field, every forest, every homestead appeared on the map exactly where the drone had photographed it. The village officials could stand at the edge of a field with a tablet, tap a marker on the map, and see the real aerial photo taken from above. The boundaries were crystal clear.

"This is way faster than manually tracing everything," he said. "And when villagers come to identify boundaries on-site, they can just look at the photos. Disputes disappear almost instantly."

Later he told me the survey resolved several historical issues: land thought to belong to the village turned out to be the neighboring village's on closer inspection; conversely, they recovered two edge plots that had been completely missed from the old ledger.

This moment made me realize that drone aerial photography + GPS mapping tools is no longer just a hobbyist's toy. It has entered the actual workflow of grassroots governance.

It Changed How I Think About Flight Logs

My old flight log was pretty traditional: time, location, weather, flight duration. But those entries were too dry—I'd forget them quickly after reading.

Now, after importing each flight's photos onto a map, my flight log becomes a visual landscape. Without any text, I can immediately see where I flew, how long I was up, and what area I covered.

Sometimes, when I look back at previous flight records, seeing those markers on the map, I suddenly remember how strong the wind was that day, or how the sunlight hit the terrain. Every point on the map is a flight memory.

Is the Free Version Enough for Drone Operators?

For an everyday drone hobbyist, the free version's 6-photo limit is honestly quite tight. A single flight typically produces dozens or even hundreds of aerial photos, and 6 is nowhere near enough to debrief an entire flight.

So for me, upgrading to the Pro version makes sense. Unlimited processing, custom image display sizes, GeoJSON export—these features are genuinely useful for drone operators.

Especially GeoJSON export. Sometimes I import flight data into flight planning software for more advanced data analysis. That feature made me feel the tool's value went far beyond its original promise.

Wrapping Up

What makes drone flying most captivating isn't how high you fly or how far you shoot—it's how you see the world from a completely different angle.

This tool didn't change how I fly. But it changed how I look at my flights. Instead of seeing a pile of scattered photos, I now see a complete flight—with a starting point, a trajectory, a covered area, and every photo's corresponding ground position.

Every time I import photos after a flight, it feels like the final step of completing the mission—placing a visual stamp on that flight.

If you're a drone operator, or just someone who loves capturing the world from above, this tool will make you redefine what "flight logging" really means.

WTSolutions — Sun, 21 Jun 2026 07:46:42 +0000

In the digital office era, document security is becoming increasingly important. Especially when batch generating sensitive documents such as contracts, agreements, and reports, ensuring these documents are not viewed or modified by unauthorized personnel is a challenge faced by every organization and individual. Today, I will introduce Sheet-to-Doc's latest feature - Batch Document Password Protection, providing enhanced security for your documents.

Official Website: https://s.wtsolutions.cn/sheet-to-doc.html

Employee files, salary information, performance evaluations, etc.
These documents involve personal privacy

4. Sensitive Reports and Proposals

Business plans, project proposals, market research reports, etc.
These documents need access control

Manually setting passwords for each document is not only time-consuming but also prone to errors or omissions. Sheet-to-Doc's batch password protection feature can automatically add password protection to each document during generation, greatly improving work efficiency and document security.
