Data converters
APIs speak JSON; spreadsheets speak CSV. Moving data between the two by hand is error-prone, especially with nested fields or commas inside values.
These converters run in your browser, so the data never leaves your device.

Questions
- What happens to nested JSON?
- Nested values are flattened into columns so each record fits on one row.
- Does CSV to JSON use the first row as names?
- Yes. The header row becomes the field names for each object.
- Is my data uploaded?
- No. Both tools run in your browser.
