JSON to PDF - Free Online Browser Tool

Convert JSON data files into a readable PDF, as a table or an indented outline.

A JSON payload is easy for a program to read and awkward for a person to check. This lays it out as either a table of records or an indented tree, so a reviewer can read what the data actually says.

This json to pdf utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the JSON to PDF Tool

Four steps, and the whole thing runs locally on your own device.

  1. Add the JSON file

    Choose a .json file, or any plain text file whose contents are valid JSON.

  2. Pick the layout

    A data table suits a list of similar records; a tree suits one deeply nested object.

  3. Read the structure

    An array of simple records becomes a header row and tab-separated rows, and anything nested becomes an indented tree instead.

  4. Save the report

    The result is a PDF of the data, which is far easier to search and print than the raw text was.

Frequently Asked Questions

What happens if the JSON is malformed?

The file cannot be parsed, so the tool reports the parser's own message rather than printing a document that would misrepresent the data.

Are the table columns named?

Yes, for an array of simple records the keys become the header row, with one row beneath it for each record in the array.

Is deeply nested data still readable?

Yes, nested objects and arrays are printed as indented lines below their key, which keeps the path to each value visible.

How much of a very long list is printed?

Up to two thousand records become rows, and a line at the end says how many further records were left out.

Is my data uploaded anywhere?

No. The file is parsed and laid out inside the tab, so a payload holding personal or commercial data stays on your machine.
