Online Random CSV Generator for Testing and Development
Finding realistic tabular data for testing shouldn't be a chore. Whether you are testing database imports or data pipelines, you can build exactly the sample files you need in seconds. Save time by selecting column types from a dropdown and setting your row count with a slider instead of manually typing rows. The workspace provides a live table preview alongside your configuration, allowing you to inspect delimiters and quoting before downloading the final file.
17 Built-in Column Data Types
Assign specific data types to every column, ranging from names and emails to prices and UUIDs. Realistic values ensure your test data passes validation rules and looks professional in client demos. You have the freedom to mix and match these types to accurately model any table schema for your project.
Upload and Preview Existing CSV Files
This tool also functions as a convenient CSV viewer for your existing files. Simply drag and drop a file or use the upload button to see your data instantly. The built-in parser automatically detects common delimiters like commas and tabs, making the workspace a versatile hub for both inspecting current data and generating new records.
Flexible Configuration for Any CSV Format
Take full control over your data with flexible configuration options. You can adjust row counts, choose delimiters, and manage headers in the General section to match your specific requirements. Adding or removing columns is straightforward in the Columns list, and built-in presets allow you to quickly load layouts for contacts or transactions. Your data rebuilds instantly every time you click the Generate button.
Table Preview and Raw CSV Views
Inspect your data through two convenient views: a scrollable HTML Table Preview or the Raw CSV text output. You can switch between these tabs at any time to verify delimiters and quoting in a formatted monospace view. Every update is reflected instantly across both panels, giving you immediate feedback as you adjust your configuration.
Download and Copy with One Click
Getting your data out is simple with one-click copy and download options. Use the Copy button to grab the text or save it as a .csv or .tsv file for your local environment. A handy stats bar keeps you informed about row counts and file sizes, so you always know exactly what you are exporting.
Free Random CSV Generator Runs Entirely in Your Browser
Your privacy is guaranteed because all processing happens entirely within your browser. Since no data ever leaves your device and no server requests are made, your sensitive schemas remain completely private. Closing the tab removes all session data, making this a secure choice for modeling customer records or financial transactions.
