JSON formatter
Format, minify, and validate JSON.
Questions
What does this tool do?
The JSON formatter pretty-prints, minifies and validates JSON. Paste an API response, a config file or a blob from a log, then choose an indent — two spaces, four spaces or tabs — to format it for reading, or switch to minify to collapse it into one compact line. When the JSON is invalid, the validator reports the exact line and column where parsing fails, so you go straight to the missing bracket or stray comma. The result can be copied or downloaded as a .json file.
Where does the error come from?
When parsing fails, the position of the failure is translated into a line and column inside your input, so you can jump straight to the offending bracket.
Is there a size limit?
Whatever your tab's memory can hold. Large documents format in a moment.
