FAQs
What does "pretty-printed" mean?
The JSON is reformatted with 2-space indentation and line breaks before going into the PDF, so nested objects and arrays are easy to read instead of one giant line.
My JSON failed validation — what now?
The error message names the problem (often a missing comma or an extra trailing comma). Fix that spot and convert again — the tool won't produce a PDF from invalid JSON.
Is my file uploaded anywhere?
No. This tool runs entirely in your browser — your JSON is never sent to any server.
