How CSV to JSON Conversion Works
The converter reads your CSV row by row:
- Row 1 (header) — becomes the keys for each JSON object
- Rows 2+ (data) — each row becomes one object in the JSON array
- Quoted fields — fields wrapped in double quotes are handled correctly, including commas inside values
- Empty cells — preserved as empty strings in the JSON output

Frequently Asked Questions
How does the CSV to JSON converter work?
The first row of your CSV is treated as the header row and becomes the JSON object keys. Each subsequent row becomes a JSON object in the output array.
Is my CSV data sent to a server?
No. All conversion happens entirely in your browser using JavaScript. Your data never leaves your device.
Does it handle commas inside CSV fields?
Yes. Fields wrapped in double quotes are handled correctly, including commas and escaped double quotes ("") inside quoted fields.
Can I upload a CSV file instead of pasting?
Yes. Click "Choose File" or drag and drop a .csv or .txt file onto the drop zone. The file contents are loaded into the editor automatically.
