100% Private, your JSON never leaves your browser. The preview and the PDF are made on your device. Nothing is uploaded to our servers.
This tool reads your JSON with its own strict parser, which gives the line and the column of each error. It keeps the order of your keys and the exact form of your numbers, so 12.50 stays 12.50. It writes the PDF with pdfmake, inside your browser. Arrays of objects become tables with a header row that repeats on each page, and nested objects become sections with headings. The PDF has vector text with the Inter font embedded, so you can select, copy and search the text.
The first time you click Download PDF, the tool downloads the PDF engine and the fonts (about 2.4 MB) from our site. After that, a PDF takes about a second. You can convert as many files as you like.
Want to make branded PDFs from JSON at scale? The Bannerbear API automates it for you. This tool makes a plain document from one JSON file at a time. With the Bannerbear API, you render branded PDFs from JSON: design a template once with your fonts and colours, then send the JSON data for each invoice, certificate or report from your app or a no‑code workflow, and get a PDF back for each one.
JSON is the text format that most APIs and apps use to send data. A JSON to PDF converter turns that data into a document that people can read, print, attach to an email or keep as a record.
Use it to share an API response, an order, a product export or a report with people who do not read code. You do not have to write a template or any code first.
The tool gives you:
You can convert a file in less than a minute. You do not need to install software or make an account.

This is how each part of your JSON shows in the PDF.
| JSON | In the PDF |
|---|---|
| Object at the top level | Label and value rows for the plain values, and a section for each nested object or array |
| Nested object | A heading with the key name, then its values. Each level gets a smaller heading |
| Array of objects | A table with a column for each key. Number columns are right aligned, and the header row repeats on each page |
| Array of strings or numbers | A bulleted list. A short list (up to 8 short values) stays in one label and value row |
| Object or array inside a table cell | Its values as Label: value lines in the cell |
| Array of mixed values | A section for each item, for example Item 1 and Item 2 |
null, true and false | As in the JSON. null is grey |
Text that starts with https:// | A clickable link |
JSON.parse.The common questions about converting JSON to PDF, and their answers
Yes. The tool is free, with no watermark, no sign up and no daily limit. You can convert as many files as you like.
No. The tool reads your JSON in your browser, and makes the preview and the PDF there too. Your data stays on your device. The page loads only the PDF engine and the fonts from our site.
An array of objects becomes a table. Each key becomes a column, in the order that the keys first appear. If an object does not have a key, its cell is empty. A long table continues on the next page, with the header row again at the top.
The tool checks your JSON with a strict parser. It shows the line and the column of the first error, the lines above it, and what to fix. Common errors are a missing comma between two values, a comma after the last item, single quotes instead of double quotes, and property names with no quotes. Click Go to line to select the error in the box.
Each nested object gets a heading with its key name, and its plain values show as label and value rows. A deeper level gets a smaller heading. Inside a table, a nested object shows as Label: value lines in its cell.
The tool always fits the columns to the page width. It gives more width to the columns with longer text, and makes the text smaller when a table has many columns. Select Landscape, or US Legal in landscape, to give the columns more room.
Yes. The PDF has vector text with the fonts embedded in the file. It is not a screenshot. You can select, copy and search the text, and the file is small.
A JSON file has one top-level value. To convert JSON Lines (one object on each line), put the objects in an array: add [ at the start, a comma at the end of each line except the last, and ] at the end.
