Frequently Asked Questions

How do I convert JSON to CSV?
Paste a JSON array of objects and click Convert to CSV. The tool creates a header from the keys and a row per object, then lets you copy or download the CSV.
Does it handle nested objects?
Yes, in a simple way: a nested object or array in a field is written back as JSON text inside that CSV cell, so no data is lost. Flatten it first if you want separate columns.
Will the CSV open in Excel?
Yes. Fields with commas, quotes or line breaks are escaped to the CSV standard, so the file opens cleanly in Excel, Google Sheets and Numbers.
Is my data uploaded?
No. The conversion happens entirely in your browser, so your JSON never leaves your device.
