Frequently Asked Questions

Is converting CSV to JSON with PDFPilot really free?

Yes. CSV to JSON is completely free to use, with no sign-up or account required.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser. Your file is never uploaded to PDFPilot's servers.

What does the JSON output look like?

An array of objects, one per row, keyed by the header row's column names — e.g. [{"Name":"Alice","Age":"30"}].

Are numbers converted to actual numbers in the output?

No — every value is kept as a string, exactly as CSV itself stores it. This tool doesn't guess which columns were meant to be numeric.

What if a row has fewer values than the header?

Missing values produce an empty string for that key in the resulting object, rather than an error.

Does this handle quoted fields with commas inside them?

Yes — the CSV parser follows RFC 4180 quoting rules, so a value like "Smith, John" inside quotes is read as one field, not split into two.
