Convert JSON to PDF Online
Convert a JSON file to a formatted PDF document using monospace layout, directly in your browser.
JSON is the lingua franca of data exchange but it is not always easy to share or review without a code editor. Converting a JSON file to PDF gives you a document you can attach to a ticket, include in a report, or print for a review meeting. Dockitt reads your .json file, formats it with two-space indentation using JSON.stringify, and lays it out in a PDF using a monospace Courier font at 10pt. This preserves the structure and readability of the JSON while making it universally accessible as a document.
How to use
- Click 'Choose JSON' and select the JSON file you want to convert to PDF.
- Click 'Convert to PDF' and wait while the file is formatted and laid out.
- Download the PDF file.
FAQ
What font and layout does the PDF use?
The PDF uses Courier (monospace) at 10pt with 40pt margins on all sides on US Letter pages (612 × 792 pt). Lines are wrapped at approximately 90 characters to fit within the page width. New pages are added automatically when content exceeds the available space.
Is the JSON reformatted or does it preserve the original formatting?
The JSON is re-parsed and reformatted with JSON.stringify using two-space indentation. This means the output always uses consistent formatting regardless of how the original file was formatted — whether it was minified, used tabs, or had inconsistent spacing. The data structure is preserved exactly.
What if the JSON file is invalid?
If the file cannot be parsed as valid JSON, the tool will show an error message. Make sure the file is valid JSON before attempting the conversion. You can validate JSON using any online JSON validator or by running JSON.parse in a browser console.
Can I convert large JSON files?
Yes, the tool supports JSON files up to 100MB. Very large files with deeply nested structures or large arrays will produce multi-page PDFs. The conversion happens in your browser, so processing time depends on the size and complexity of the file.
Will Unicode characters in the JSON values display correctly?
The PDF uses Courier, which covers the standard Latin character set. ASCII characters and common Western European characters will display correctly. Unicode characters outside the Courier character set (emoji, CJK, Arabic, Cyrillic, etc.) will not render. If your JSON values contain non-Latin characters, the text content will be present but some characters may appear as missing glyphs.
Is the conversion done in my browser or on a server?
The conversion runs entirely in your browser using pdf-lib. Your JSON file is never uploaded to any server. The PDF is generated locally on your device and downloaded directly from your browser.
