No limits on number of files you can process
A Batch JSON Processor is a tool that allows you to process multiple JSON files simultaneously instead of one at a time. You can upload dozens or even hundreds of JSON files and format, minify, or validate them all with a single click. This is perfect for developers who need to process large batches of JSON configuration files, API responses, or data exports efficiently.
You can upload and process unlimited JSON files in a single batch. The tool efficiently handles everything from a few files to hundreds of files. All processing happens in your browser, so the practical limit depends on your device's available memory. For best performance, we recommend processing files in batches of 100 or fewer at a time.
Yes, your data is completely secure. All JSON processing happens entirely in your browser using client-side JavaScript. Your files are never uploaded to any server, and no data leaves your device. This ensures complete privacy and security for sensitive JSON data like configuration files or API keys.
The Batch JSON Processor offers three main processing modes: (1) Format/Beautify - adds proper indentation and formatting to make JSON readable, (2) Minify/Compress - removes all whitespace to reduce file size for production use, and (3) Validate - checks all files for valid JSON syntax without modifying them. Each mode can be customized with options like indentation size, key sorting, and comment removal.
Yes! After processing your JSON files, you can download all successfully processed files with one click. Each file retains its original name and is downloaded individually. You can also download files one by one if you prefer. The tool shows you exactly which files succeeded and which had errors before downloading.
The Batch JSON Processor handles errors gracefully. If some files contain invalid JSON, those files will be marked with an error status and display the specific error message. Valid files will still be processed successfully. You can download only the successfully processed files and fix the errored ones separately.
Absolutely! When using Format mode, you can customize indentation (0-8 spaces or tabs), choose to sort object keys alphabetically, and enable comment removal. For Minify mode, you can also choose to remove comments. All files in the batch will use the same settings for consistency.
Yes, the Batch JSON Processor provides real-time feedback during processing. You'll see a progress bar showing overall completion, individual file status indicators (pending, processing, success, or error), and statistics showing how many files succeeded or failed. Each file displays its original size and processed size along with the compression percentage.
