CSV to JSON Converter

Upload CSV file
 .csv / .xlsx / .zip up to 1 MB (50 MB PRO)

This online tool converts CSV to JSON. You may also convert XLSX (Excel files) to JSON here as well. The first row of the CSV file must contain column headers. Place double underscore within the column header name to create nested data. For example HeaderTitle__ChildData__SomeAttribute.

You may wish to convert your JSON result back to CSV (or XLSX) again, using our JSON to CSV Converter
