Frequently asked questions
Is the JSON to CSV converter free?
Yes, completely free, with no account and no limits on use.
Is my JSON uploaded to convert it?
No. The conversion runs fully in your browser, so your data is never sent to a server and stays private.
What JSON shape works best?
An array of objects converts cleanly: each object becomes a row and each key becomes a column. Nested objects are flattened into dotted column names, and the column set is unioned across all rows so nothing is dropped.
How are commas and quotes handled?
Values containing commas, quotes, or line breaks are automatically wrapped in quotes and escaped per the CSV spec (RFC 4180), so the file opens correctly in Excel and Google Sheets.
Is there a size limit?
No hard limit. It runs locally, so the practical ceiling is your device’s memory. Large arrays convert quickly.
How do I host or share the CSV?
Click Publish and the generated .csv file is live at its own HTTPS link in seconds, a quick way to hand a data export to a colleague without email attachments.
