Common JSON problems

Missing commas, trailing commas, unescaped quotes, wrong brackets, and copied smart quotes can break JSON. Formatting makes structure easier to inspect before using data in an app or API call.

Format vs. minify

Formatted JSON is easier for humans to read and debug. Minified JSON removes whitespace for compact storage or transmission.

Privacy note

Use local formatting for routine data, but avoid pasting secrets, access tokens, private customer data, or production credentials into any browser you do not control.

Practical workflow

Format first, fix any validation issue, then minify only after the data is correct. Keep an original copy if you are editing a production configuration.

How to use it

1. Paste JSON into the input area.
2. Format or minify the data.
3. Review validation messages before copying the result into your project.
