Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
Random CSV Generator creates spreadsheet-ready test data from columns you define. Name each column, choose its data type, pick how many rows you need and select a delimiter (comma, semicolon, tab or pipe). It outputs a proper CSV with a header row and correctly escaped values you can copy into Excel, Google Sheets, a database import or a test fixture. All generation happens locally in your browser, so nothing is uploaded.
Short answers for the questions people usually have before trying a utility like this.
