JSON to XML & XML to JSON Converter
A two-way conversion tool for JSON and XML data structures, designed for development, testing, and data processing.
When JSON data contains excessive spaces, line breaks, and indentation, the file size increases significantly, which can impact transfer and storage efficiency. A JSON minifier works by removing all whitespace characters (including spaces, tabs, and line breaks) that do not affect the data structure or semantics. This converts formatted, multi-line JSON into a compact, single-line string, thereby reducing data size and accelerating network transmission. The tool processes JSON strings compliant with the RFC 7159 standard, outputting minified JSON that is semantically identical but much smaller in size.
Can the minified JSON still be parsed normally?
Yes. Minification only removes whitespace characters and does not affect the JSON semantics. All standard parsers can process it normally.
What is JSON minification?
JSON minification is the process of reducing file size by removing all non-essential whitespace characters (spaces, line breaks, tabs), such as converting multi-line indented JSON into a compact single-line format.
Please ensure your input is in a valid JSON format, otherwise the processing may fail. Minification will remove all formatting information; if you need to reformat it, please use a JSON Beautifier tool. This tool does not perform data encryption or binary compression like Gzip. Please be mindful of privacy and security when handling sensitive data.
For API data transmission, we recommend using formatted JSON in development environments for easier debugging, and minified JSON in production environments to boost performance. Typical example: A multi-line indented JSON input (e.g., {"name": "test", "value": 123}) will be output as a compact single-line format (e.g., {"name":"test","value":123}), reducing the file size by approximately 20% to 50%.
