Text and local files

Paste text, or open a local UTF-8 TXT, CSV or JSON file. The app reads the file in your browser. The file and its name do not go to a server.

Pasted text can have up to 100,000 characters and 512,000 bytes. A file can have up to 512,000 bytes.

The app decodes CSV cells and JSON strings and shows each field for review. Select passages inside one field only.

Choose the output format. The app checks the saved file again before it gives the file to you.

The app refuses JSON numbers, duplicate JSON keys and CSV cells that look like formulas.

PDF, DOCX, images and OCR are not supported. The app refuses these files and does not process part of them.

Restore works with reply text only. It does not recreate an original file.

The interface is in English and Russian. Profiles add rules for Russia, the USA, the UK and medical text.

A supported format does not mean that the app finds every personal detail. Review every field.
