A CSV (comma-separated values) file stores data in a table structure, with each row on a new line and each value separated by a comma. CSV files are widely used for importing contact lists, uploading data to tools like Lusha, and managing large datasets.
You can create one using Microsoft Excel, OpenOffice Calc, or Google Sheets.
How to create a CSV file
Open a new spreadsheet in Excel, OpenOffice Calc, or Google Sheets.
In row 1, type your column headers — for example: First Name, Last Name, Email, Company.
Enter your data in the rows below each header.
Click File → Save As. (In Google Sheets, go to File → Download as.)
From the file type dropdown, select CSV.
Click Save. Commas will automatically be added between each value.
Your file is now ready to upload.
