Frequently asked questions
- How are columns mapped to JSON keys?
- The first row of your CSV is treated as the header row, and its values become the object keys for every following row.
- Does this handle quoted fields with commas or newlines inside them?
- Yes — quoted fields ("like, this") are parsed correctly, including embedded commas, newlines, and escaped "" quotes.
- Is my CSV sent to your servers?
- No. The conversion runs entirely in your browser, whether pasted or uploaded as a file.
