Dummy CSV is a free online DocxWave tool for csv & data. Generate a dummy CSV with any column and row count in your browser — no signup, no upload.
Dummy CSV builds a valid comma-separated file in your tab. Set columns and rows, optionally pick a delimiter or Excel BOM, and download. Nothing is uploaded.
You can use it on a phone, tablet, or computer. There is no sign-up, and processing runs in your browser so files and text are not uploaded to DocxWave for storage.
How Dummy CSV is useful
Importers, upload forms, and QA checks need a known table without inventing spreadsheet data. Generating locally means you get exactly 3×1,000 or 50,000 rows in one click.
Typical reasons people open this tool:
- Finish a one-off job without installing desktop software
- Keep documents and copy on the device they already use
- Move faster than emailing a file to themselves or waiting on IT
- Pair it with other CSV & Data on DocxWave in the same sitting

Practical tips
- Leave the filename as testfile to get dummy-1000-rows.csv.
- Turn on Excel BOM if Excel opens the file with garbled headers.
- Very large tables (tens of thousands of rows) can take a moment — start smaller if the tab stalls.
Why use DocxWave for this
Many “free converters” ask you to upload a file to a server you do not control. DocxWave is built around browser-side processing: you open the page, do the work, and download or copy the result. That is the difference when the file is a payslip, a contract, a customer CSV, or a draft that is not public yet.
You also get a consistent layout across PDF, Word, image, CSV, and text tools, so the next job does not require learning a new app.
Frequently asked questions
Is Dummy CSV free?
Yes. You can use it without creating an account or paying a subscription.
Are my files uploaded?
No. Processing runs locally in your browser. DocxWave does not need your file on a server to run the tool.
Does it work on mobile?
Yes. Use a modern mobile or desktop browser. Very large files are more comfortable on a laptop because they use more memory.
Can beginners use it?
Yes. Follow the steps above. If something looks wrong, keep the original file and try a milder setting (for example less compression).
