CSV (Comma-Separated Values) is a simple file format used to store tabular data, such as a spreadsheet or database. Each line of the file is a data record, consisting of one or more fields, separated by commas.
CSV files created with our tool can be imported into spreadsheet applications (like Microsoft Excel or Google Sheets), databases, CRM systems, or any other application that accepts CSV format. They're perfect for testing, data migration, and creating sample datasets.
While there's no hard limit set by our tool, browser performance may decrease with extremely large datasets (tens of thousands of rows). For optimal performance, we recommend generating up to 10,000 rows at a time.
No, all data generation happens entirely in your browser. We don't send your data to our servers or store any of the content you create. Your data remains completely private.
Our CSV Creator tool is completely free to use. No signup or account required.
