What is JSON Formatter?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. Our JSON Formatter is a free online tool designed to help developers beautify, validate, and minify their JSON data.
Key Features of our JSON Tool
- Prettify JSON: Convert messy, single-line JSON into a readable, indented structure.
- Validate JSON: Automatically check for syntax errors like missing commas or mismatched brackets.
- Minify JSON: Remove all whitespace and newlines to reduce data size for production environments.
- Client-Side Processing: Your data never leaves your browser, ensuring maximum privacy and security.

Frequently Asked Questions (FAQ)
Is my JSON data kept private?
Yes. Our JSON Formatter works entirely on the client-side. We do not store, log, or transmit your data to any servers. Your sensitive data remains in your browser.
Can this tool fix broken JSON?
It can identify syntax errors (like missing quotes or commas) and point you to the exact line. It won't automatically fix them to avoid changing your data's intent.
What is the difference between Format and Minify?
Format adds indentation and newlines to make JSON readable for humans. Minify removes all whitespace to reduce the file size for machine processing and production.
Does it support large JSON files?
Yes, it can handle large files efficiently using your browser's native parsing capabilities. However, extremely large files (multi-gigabyte) may be limited by browser memory.
Is there a limit on the number of fields?
No, there is no hard limit on the depth or number of fields in your JSON object.
