Text Processing Collection
Online Text Processing Tools
Stats, cleaning, generation, regex, Markdown, summaries and charts — common text jobs in one place.
A text-focused toolkit for editors, QA engineers, operators and developers: character statistics, string obfuscation, Markdown preview, regex testing and memo cards, duplicate and empty-line removal, batch replacement, URL and email extraction, fake-data and placeholder generation, text-to-speech, OCR, and turning text data into charts. Everything runs locally in your browser; pasted content is never uploaded.

Suggested workflows
Data cleanup
Extract the fields you need, then dedupe, remove blank lines, batch replace, and finally measure the result.
Regex debugging
Fine-tune a pattern on real samples, then save it to a memo card for later reuse.
Content production
Draft with placeholders and fake data, review in Markdown preview, then export charts or speech when ready.
Why a text hub helps
Batch first, refine second
When cleaning spreadsheet exports or logs, start with dedupe, blank-line removal and batch replace, then use the regex tester for precise matches. Save tuned patterns as memo cards to reuse next time.
Repeated small jobs in one place
Deduping, replacing, extracting and counting are routine when handling logs, spreadsheet exports and user data — one page beats opening several scripts.
Regex and memos form a loop
Debug a pattern online, save it as a card, and reuse it next time instead of re-learning the syntax.
Local processing protects privacy
Logs, contact lists and draft content often contain sensitive data; browser-local processing avoids sending them to third-party services.
Text tools FAQ
Which regex syntax do you support?
The tools use the JavaScript regex engine with named groups, lookaheads and other modern features; cross-language differences still depend on your target runtime.
Does the dedupe tool keep line order?
Yes. The first occurrence of each line is kept in the original order, so the result stays easy to cross-check.
Do text-to-speech and OCR require a network?
Core features run locally. If an online voice or recognition service is used, the page will tell you and ask for confirmation first.
