Text & data converter
JSON, CSV, TSV, and Base64 transformations stay in this tab.
Nothing leaves this tab.
Understanding the data modes
Pretty JSON adds indentation for review, while minified JSON removes optional spacing. Both JSON modes first parse the input, so invalid syntax produces an error instead of silently changing the data. Base64 is an encoding format, not encryption, and should never be used to hide confidential information.
CSV and TSV limitation
The delimiter switch is intended for simple rows. Quoted fields containing commas, tabs, or line breaks require a full spreadsheet parser. Always inspect converted rows before importing them into another system.
Privacy and verification
Conversion runs in this browser tab. The site does not intentionally upload the pasted value. Test a small sample first, keep the source copy, and compare column counts after a delimiter conversion.
