Validate and pretty-print JSON quickly. Catch syntax errors, read nested structures and make your data tidy with the free Bagiqo JSON validator.
JSON is everywhere — in APIs, configuration files and saved browser data. A single missing comma or an extra bracket can stop an entire integration from working. The fastest way to find that mistake is to run the text through a validator.
The JSON validator and beautifier takes your JSON, checks it for errors, and reformats it in a readable, indented layout. If anything is wrong, you get a clear hint about where the problem is so you do not have to scan every line by hand.
How to use it
- Open the JSON tool.
- Paste your JSON into the box.
- Submit and read the result: a clean, formatted document, or an error message pointing at the issue.
When this helps
- Debugging a response from an API you are building or testing.
- Cleaning up a minified config file before you edit it.
- Making nested data legible for a colleague or reviewer.
The validator is entirely free and needs no sign-up. Keep a copy of it next to your other developer utilities like the SQL formatter.
