Is converting YAML to JSON with PDFPilot really free?

Yes. YAML 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, using a real YAML parser. Your file is never uploaded to PDFPilot's servers.

Does this support nested YAML structures?

Yes — unlike this project's CSV/Excel-focused conversion tools, YAML naturally supports nested objects and arrays, and the JSON output preserves that same nested structure.

What YAML features are supported?

Standard YAML 1.1/1.2 syntax — mappings, sequences, scalars, anchors and aliases, and multi-document handling of the first document in a file.

What happens if my YAML has a syntax error?

You'll get a clear error message describing what couldn't be parsed, rather than a broken or partial JSON output.
