As developers, we constantly deal with text transformation tasks —
encoding a string, cleaning up CSV data, converting between formats.
Most of us either Google a Stack Overflow answer, write a throwaway
script, or paste sensitive data into some sketchy online tool.
There's a better way.
I've been using TextTooling.com for these
tasks. Everything runs 100% in the browser — no data is sent to any
server. Here are the tools I reach for most often:
1. URL Encoder / Decoder
Stop manually escaping query string parameters. Paste your string,
get the encoded version instantly.
2. Base64 Encoder / Decoder
Useful when debugging JWTs, API payloads, or image data URIs.
3. HTML to Text Converter
Strip all HTML tags from a string — great for cleaning scraped content
or sanitizing user input before logging.
4. Remove Duplicate Lines
Pasting a list of IDs or values and need to deduplicate?
This handles it in one click.
5. Sort Lines
Alphabetically sort any list — useful for normalizing imports,
config values, or enum entries.
6. Whitespace Remover
Trim extra spaces, tabs, and blank lines from messy text or
copy-pasted content from PDFs and docs.
7. Word / Character Counter
Quick sanity check on string lengths before hitting API limits
(OpenAI, Twitter, SMS gateways).

8. Comma to Column / Column to Comma
Convert CSV data to a vertical list and back. Saves time when
preparing SQL IN clauses or Excel imports.

9. Hex to Text Converter
Debugging binary data or working with color values?
Convert hex strings back to readable text instantly.
10. Remove Line Breaks
Paste a paragraph from a PDF that came in with hard line breaks
after every 80 characters. One click fixes it.
Why browser-based matters
Most online tools send your input to a backend server. That's fine
for public data, but not ideal when you're pasting:
- API keys or tokens (even partial ones)
- Customer data or PII
- Internal config values
- Proprietary code snippets
With client-side tools, the data never leaves your machine.
No logs, no storage, no risk.
