What this tool does
CSV to JSON converts comma-separated data into JSON in your browser — handy for feeding spreadsheet exports into code or APIs.
How to use
- Paste your CSV into the input box.
- Choose whether the first row is a header, and pick the delimiter.
- Click Convert to JSON and copy the result.
Notes
- Everything runs locally — your data is never uploaded.
- All values are kept as strings, matching the CSV source.
Frequently asked questions
Does it handle quoted fields and commas?
Yes. Quoted fields, escaped quotes (""), and newlines inside quotes are parsed correctly.
What does 'First row is header' do?
When on, the first row becomes the object keys and you get an array of objects. When off, you get an array of string arrays.
Is my data uploaded?
No. Conversion runs entirely in your browser.
