GOOD TO KNOW

Frequently asked questions

Does minifying change values inside strings?

No. JSON is parsed and serialized; whitespace inside string values is retained.

Can I minify invalid JSON?

No. Syntax errors must be corrected before the tool can produce a result.

Are comments supported?

No. Standard JSON does not allow comments. Remove them before running this tool.

Can very large numbers change?

JavaScript number precision applies when parsing JSON. Keep identifiers and integers requiring exact precision as strings.
