Frequently Asked Questions

Does the converter infer data types?

Yes. Numbers stay as numbers, true/false become booleans, and empty cells become null. Everything else is treated as a string.

What if my CSV has commas inside fields?

Quoted fields are handled correctly. A value like "Smith, John" is treated as a single string and the inner comma is not used as a delimiter.

Does it need a header row?

Yes. The first row is used as the keys for each JSON object. Make sure your CSV has descriptive column headers for clean output.

Can I use this for spreadsheet exports?

Yes. Export your spreadsheet as CSV from Excel, Google Sheets, or Numbers, paste it here, and get a JSON array you can use directly in your app.

Is the tool free?

Yes, completely free with no account required.
