Good data. In the right format.
Make JSON readable, trim it down, or move between JSON and CSV. Your data stays in your browser.

A little structure helps
JSON to CSV accepts an array of objects. All keys become columns, missing values become empty cells, and nested objects are stored as JSON strings.
Keep your values intact
CSV needs a unique header for each column. Quoted commas, quotes, and multiline cells are supported. CSV values stay strings, preserving leading zeroes.
Safer spreadsheet exports
Formula protection prefixes cells beginning with =, +, −, or @ with an apostrophe. Disable it only when you need the original values and trust the data. Very large JSON numbers may lose precision; quote identifiers.
