Convert JSON to CSV
Turn a JSON object array into CSV.
Spreadsheet conversion runs locally. CSV and TSV export the first worksheet and neutralize formula-like text.
Your file is processed on your device and is not uploaded to our servers.
When to use it
Use JSON → CSV to move tabular data into a program that accepts CSV. Input must be a list of flat objects, for example [{"name":"Ana","score":10}]; nested structures are not expanded.
What changes in the result?
Only the first worksheet is exported. Colors, charts, macros and executable formulas are not retained. CSV uses commas and TSV uses tabs. Check dates, leading zeros and formula-like text before importing.
If conversion does not work
Compare a few output rows with the original before using the data. Encrypted files, incompatible structures or oversized workbooks may be rejected. A low-memory phone may need a smaller file.
