Data tools

Data tools that parse and convert files on your device. Spreadsheets become JSON, structure stays honest, and the file contents never leave your browser.

CSV JSON CSV to JSON Turn spreadsheet exports into clean JSON for scripts and apps. Text PNG QR code generator Turn a link or any text into a downloadable QR code. JSON JSON JSON formatter Validate, pretty-print or minify JSON without sending it anywhere. Text Stats Word counter Live word, character and reading-time counts as you type. TXT Base64 Text to Base64 Encode text or a .txt file as Base64, right in your browser.

Which tool do I need?

I exported a spreadsheet and need JSON

CSV to JSON parses Excel, Google Sheets and LibreOffice exports, with delimiter auto-detection and proper handling of quoted fields.

My JSON output looks wrong for scripts

Pick the "Rows" shape for a raw grid of text cells, or "Objects" for records keyed by your header row. Numbers become numbers; postcodes stay strings.

The file uses semicolons or tabs

Auto detection handles comma, semicolon and tab delimiters, including the French-style semicolon CSVs Excel produces.
