JSON Formatter
Format, validate and minify JSON locally.
What this tool does
JSON is a structured text format used by APIs and configuration files. Formatting makes nested data easier to read, while validation reports syntax errors that prevent parsing.
How JSON Formatter works
- Choose a file or enter the value you want to work with.
- Set the available options for the result you need.
- Run the tool, review the result, and download or copy it.
Tips and limitations
Formatting does not verify that the data is correct for a particular application. Avoid pasting secrets such as API keys into tools unless you understand the processing environment.
Privacy and file handling
Most tools on The Tools Kit process selected files or text in your browser without sending them to our server. The AI Image Enhancer can send a selected image to a configured processing provider when enabled. Read the Privacy Policy before using that feature with personal or confidential material.
