Frequently Asked Questions
How does the JSON to PDF converter work?
Our converter uses client-side JavaScript to parse your JSON data and generate a PDF document directly in your browser. Simply paste your JSON data into the input field, configure your PDF settings, and click convert. The tool automatically formats the JSON data into a readable PDF structure with proper indentation and syntax highlighting.
Is my JSON data secure when using this tool?
Yes, absolutely. All processing happens entirely within your browser – no data is sent to any external servers. Your JSON content never leaves your device, making this tool completely secure for sensitive or confidential data. We don’t store, log, or have access to any of your information.
What JSON formats are supported?
The tool supports all valid JSON formats including nested objects, arrays, strings, numbers, booleans, and null values. It can handle complex JSON structures with multiple levels of nesting, making it perfect for API responses, configuration files, database exports, and any other JSON data you need to convert.
Can I customize the PDF output format?
Yes, you can customize several aspects of the PDF output including page size (A4, Letter, Legal, A3), orientation (portrait or landscape), font size (8pt to 16pt), and add a custom title. The tool automatically formats the JSON with proper indentation and maintains the hierarchical structure for easy reading.
What happens if my JSON has syntax errors?
The tool includes a built-in JSON validator that checks your syntax before conversion. If there are errors, you’ll see specific error messages indicating what needs to be fixed. You can also use the Format button to automatically clean up and properly indent valid JSON data.
Is there a file size limit for JSON conversion?
While there’s no strict file size limit, very large JSON files may take longer to process and could potentially cause browser memory issues. For optimal performance, we recommend keeping JSON files under 10MB. The tool handles most typical use cases including API responses, configuration files, and data exports without any issues.
Can I use this tool offline?
Once the page is loaded, the core functionality works offline since all processing happens in your browser. However, you’ll need an internet connection for the initial page load to download the necessary JavaScript libraries. After that, you can bookmark the page and use it without an internet connection.
What browsers are supported?
The tool works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. It’s fully responsive and works on desktop computers, tablets, and mobile devices. For the best experience, we recommend using the latest version of your preferred browser.
