JSON and CSV. Format JSON, turn a CSV table into JSON, or turn a list of JSON objects into CSV on this device.
The data stays on this device. Nothing is uploaded.
Limitations
The limit is 1,000,000 characters. CSV uses the header row. A JSON list for CSV must contain objects. Invalid input stops with an error.
How it works
- Type, paste, or choose a local file when the tool asks for one.
- Review the count or the change.
- Copy or download. The source stays on this device.
Questions
Is my file uploaded?
No. JSON and CSV runs in this browser and the file is not sent.
Which CSV shapes work?
A header row, commas or semicolons, and quoted cells. Each data row needs the same number of columns.
What JSON becomes CSV?
A list of objects. Nested values that are not text, numbers, true, false or null are refused.
