Frequently asked questions

Does it handle quoted CSV fields?

Yes. Fields wrapped in double quotes may contain commas and newlines, and doubled quotes inside them become a single quote.

Are values converted to numbers?

Integers, decimals, true/false and empty cells are auto-converted to JSON numbers, booleans and null. Everything else stays a string.

Is my CSV file uploaded?

No. The conversion runs in your browser, so sensitive spreadsheet data never leaves your device.

Does it support nested JSON in cells?

No, each cell becomes a flat string or number. For nested output, restructure the CSV first.
