What Create a Random CSV can do:

This tool is perfect for generating quick CSV test data without needing a spreadsheet or script. You control how big the file is and whether it has headers. All values are short, random alphanumeric strings great for simulating datasets, filling tables, testing import tools, or benchmarking software. It’s fast, fully browser-based, and export-ready.

Example:

With 3 columns and 2 rows:

Column1,Column2,Column3
x8mjd,4lpak,z9sfu
dkwq1,8fwoe,bwz73

If you disable the header:

x8mjd,4lpak,z9sfu
dkwq1,8fwoe,bwz73

Common Use Cases:

Generate mock data for software testing, spreadsheets, frontend demos, or placeholder datasets. It’s useful when you just need valid CSV structure not real data for developing tools, loading tables, or testing import/export features.

Useful Tools & Suggestions:

If you need to fill it with believable content, try Generate Fake Text for names or cities. And once it’s built, run Validate CSV to make sure the structure holds up before using it anywhere.
