JSON numbers use JavaScript precision. Quote large identifiers to preserve their digits. Duplicate object keys keep the last value.
{ "name": "Ada", "count": 2 }What is JSON Minifier?
Remove unnecessary whitespace from valid JSON.
Minification removes insignificant whitespace. Spaces inside strings remain intact. The output can be copied or downloaded as JSON.
Why use JSON Minifier?
Use this tool to inspect a small dataset or prepare data for another application without installing software. Processing takes place in this browser. No account is required.
How to use JSON Minifier
- Paste your input, upload a file, or load Sample Data.
- Choose any applicable options and select Minify.
- Review the output, then copy or download it.
Example
Input
{
"name": "Ada",
"count": 2
}Output
{"name":"Ada","count":2}Common problems
Minification is not compression or encryption. Invalid JSON must be corrected before it can be minified. Numeric precision follows JavaScript.
