Frequently asked questions

What does this CSV to JSON converter do?

It reads a CSV table, uses the first row as field names, and converts each following row into a JSON object.

Does the CSV need a header row?

Yes. The first row should contain column names. Empty column names are replaced with generated names like column_1.

How does this help with mock data?

It lets you turn spreadsheet-like sample data into JSON fixtures that can be pasted into apps, API mocks, tests, or frontend prototypes.
