About this csv to json converter

The CSV to JSON converter turns rows and columns into structured JSON arrays that are easier to use in scripts, imports, and tests. It is designed for small to medium datasets where you need quick conversion without uploading files to a server.

Common uses

  • Convert spreadsheet exports into JSON fixtures.
  • Prepare tabular sample data for prototypes.
  • Inspect quoted CSV values and custom delimiters before writing import code.

Practical notes

Check the header row before converting because field names become JSON keys.

For very large files, prefer a local script or database import process with streaming support.

What delimiters are supported?
