    The details

    What happens when you convert structured data to PDF

    JavaScript Object Notation. The default way machines exchange structured data. The data is laid out as a document — usually a title, a table of the records, and the fields of each record below it. The result is a the portable document format. fixed layout, universal, and the reason everyone can open the file you send them, produced entirely inside your browser.

    What survives

    • Every value
    • The column order

    What changes

    • The structure becomes a page layout, so it is no longer machine-readable
    • Type information — a date becomes a date, but the type is now in the formatting

    Where it goes wrong

    • A thousand rows produce a very long document, and a table wider than the page gets cut off

    Why anyone would do this

    A table of numbers that somebody can read, sign and file.

    About the format

    JavaScript Object Notation.

    Text made of objects, arrays, strings, numbers, booleans and null, with a syntax borrowed from JavaScript but with no code in it.

    Where it is good
    • Readable as well as parseable
    • Maps almost exactly onto objects in every major language
    • Strict about its types, so mistakes surface immediately
    Where it falls short
    • No comments
    • No way to refer to the same piece of data twice
    • Not for very large files — the whole thing is usually held in memory
    You will find it on
    Web APIs, config files, data pipelines, every modern app

    The thing people miss

    JSON has no trailing commas and no comments, which is the two things people try to add to it most often — and which break every strict parser.

    About the target

    The portable document format.

    A tree of objects describing pages, fonts, images and scripts, with a cross-reference table and a file trailer. Text and vector graphics are stored separately from the page layout.

    • Looks identical on every operating system and every device
    • Holds text, images, vector art, forms, signatures and 3D
    • Can be locked, compressed, tagged for accessibility and archived as PDF/A

    Questions

    JSON conversion questions

    What actually happens to my JSON file when I convert it to PDF?

    The data is laid out as a document — usually a title, a table of the records, and the fields of each record below it. So the JSON file is unpacked, the content is laid out, and the result is written out as PDF. Every value survives unchanged.

    Will converting JSON to PDF reduce the quality?

    For this particular conversion, not in the way you would expect. Every value — the JSON content is not re-encoded in a lossy way. The only thing that changes is the format it is stored in.

    Is my JSON file uploaded to a server?

    No. This JSON to PDF conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your JSON file on any server.

    Do I need an account or will there be a watermark?

    Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.

    What is the most common mistake people make when converting JSON to PDF?

    A thousand rows produce a very long document, and a table wider than the page gets cut off

    Why would somebody convert JSON to PDF at all?

    A table of numbers that somebody can read, sign and file. In short: an api response you want to look at properly

    Something most people do not know about JSON?

    JSON has no trailing commas and no comments, which is the two things people try to add to it most often — and which break every strict parser.
