How to format JSON
- Paste or type JSON into the input area.
- Choose an indent width, then select Format or Minify.
- Invalid JSON shows the exact line and column of the error.
- Copy the result or download it as a .json file.
Why use this JSON formatter?
Formatting and validation happen entirely in your browser, so pasted data — which may include API keys or internal structures — never leaves your device. Syntax errors point at the exact line and column instead of a generic message.

Frequently asked questions
Is my JSON uploaded anywhere?
No. Formatting, validation, and minifying all happen locally in your browser. Nothing you paste is sent to Inqita or stored.
What happens if my JSON is invalid?
The exact line and column of the syntax error are shown, computed from your browser's own JSON parser.
What is the difference between Format and Minify?
Format adds indentation and line breaks for readability. Minify removes all unnecessary whitespace to produce the smallest possible output.
Can I choose the indent width?
Yes. Choose 2 spaces, 4 spaces, or a tab before formatting.
Does this work on mobile?
Yes. The input and output areas adapt to mobile screens.
