How it works

CSV to JSON conversion is essential for developers working with data exports. This tool splits your CSV by line and then by delimiter, mapping each value to a key defined in the header row.

It also attempts to "infer" types—meaning if a value looks like a number or a boolean, it will be stored as such in the JSON rather than as a string.

FAQ

Can I use different delimiters?

The tool currently detects commas by default. For semicolon or tab-separated values, ensure the input follows standard escaping rules.
