If you work with data — as a developer, marketer, translator, or analyst — you've felt this pain:
- A client sends you a JSON file and asks for a CSV
- You need to check if a translation actually matches the original
- You're staring at a 500-character URL trying to figure out which UTM parameter is broken
These tasks aren't hard. They're just tedious.
The fix? Stop doing them manually. Here are 5 web-based tools that handle these tasks in seconds — no install, no signup, free.
1. JSON to CSV Converter
Every developer knows this workflow: call an API, get JSON back, try to format it in Excel, mess up the column alignment.
AIXHDD's JSON to CSV Converter handles this in one click. Paste your JSON, preview the table, download as CSV. Handles nested objects and 1000+ record datasets.
2. URL Parameter Extractor
Debugging UTM tracking? Investigating a broken redirect? Trying to decode a 300-character affiliate link?
AIXHDD's URL Parameter Extractor parses the entire query string in one paste. Breaks down all key-value pairs, handles URL-encoded characters, and exports as JSON.
3. Translation Checker
If your site serves multiple languages, you need to verify translation quality.
AIXHDD's Translation Checker compares source vs target text side by side with a similarity score. Great for sanity-checking auto-translated blog posts and ad copy.
4. Keyword Density Checker
Keyword frequency matters for SEO. Too few repetitions = missed opportunity. Too many = spammy.
AIXHDD's Keyword Density Checker analyzes your text and shows frequency distribution with stop word filtering. Useful for e-commerce product descriptions and SEO content.
5. Aspect Ratio Calculator
Creating YouTube thumbnails or social media graphics? Aspect ratio math is a constant headache.
AIXHDD's Aspect Ratio Calculator comes with 12 presets (16:9, 4:3, 1:1, 9:16, etc.) plus custom input. Enter your dimensions and get the result instantly.
Why These Tools?
All 5 tools run entirely in your browser. No data is uploaded to any server. Zero signup, zero limits, zero cost. They're built for developers who need quick solutions without adding another SaaS subscription.
