For developers

JSON Formatter formats, validates and minifies JSON, lets you pick the indent and points to the line of an error. Regex Tester shows matches and groups as you edit the pattern. Base64 and URL encoding and decoding, a UUID generator for v4 and v7 and Lorem Ipsum placeholder text are here as well.

Fixing and extracting

Text Encoding Converter turns GBK, Big5 and other old encodings into UTF-8, which cures most garbled TXT, CSV and subtitle files. Extract Emails, Links and Numbers pulls contacts out of a block of text, and Password Generator makes strong passwords.

FAQ

Text & Data Tools: questions and answers

Do these text tools send my text anywhere?
No. They run entirely in your browser, so drafts, contracts, code and customer lists stay on your device.
Is there a limit on how often I can use the text tools?
No. Browser tools don't count toward the daily task limit, and none of them needs an account.
Does the Word Counter handle Chinese?
Yes. Each Chinese character counts as one word, as in Microsoft Word, and English words in the same text are counted alongside them.
How do I fix text that turns into gibberish?
Open the file in Text Encoding Converter, which guesses the original encoding, such as GBK or Big5, and shows a preview. When the preview reads correctly, save it as UTF-8.
How do I remove line breaks from text copied out of a PDF?
Paste it into Text Cleaner and tick Join broken lines. Sentences split across lines are rejoined, and genuine paragraph breaks are kept.
