Perkforge
How it works
Paste JSON, then format it with indentation, minify it for transport or download the cleaned result as a JSON file. Nothing is uploaded and no account is required.
Useful to know
JSON is a common text format used by APIs, configuration files and exported settings. Formatting changes whitespace only; it does not alter valid values.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
