Practical ways to use this tool
Technical review
Review test output
Inspect keys, values and nested structures in a PDF copy that can be shared with a review team.
Students
Prepare a structured-data example
Format a JSON exercise for submission while preserving its source values rather than turning it into a table.
Features and controls
Edit source beside its print preview
Upload or paste content, then switch between source and preview tabs.
Editing, validation and preview
Syntax coloring, find/replace, undo/redo, copying and source download support preparation before printing. Errors point to the source location so you can correct the document. The local preview reflects document styling and pagination; Start sends the validated content to the server to create a searchable PDF.
Format JSON without changing values
Choose formatted or as-written output with two- or four-space indentation.
Lossless formatting and JSON validity
The formatter retains number spelling, large integers, key order, duplicate keys and escape sequences instead of converting everything into JavaScript numbers. Formatting changes whitespace outside strings. Invalid JSON must be corrected before export. This prints the JSON source; it does not turn arbitrary nested objects into a designed report or spreadsheet.
Style a readable source listing
Choose colors, font, size and line numbering for the PDF.
Typography and listing layout
Set a color style, sans-serif/serif/monospaced font, size and bold. Line wrapping, line spacing, line numbers, page numbers and a title help readers follow the listing. Choose paper, orientation and margins for long lines. Automatic or explicit text direction supports Arabic and other right-to-left content.
Review your finished PDF
Preview the result before downloading and sharing it.
Preview, download and revise
Select Start when the settings are ready. On the result screen, Preview opens the generated PDF and Download saves a separate copy. Back returns to the current workspace; Start over clears it for a new file. Review small text, page edges and page order in the finished copy. A new PDF does not preserve the validity of an existing digital signature.
