# Add Row
The Add Row action creates a new row in an existing spreadsheet. To get started, [Authenticate](https://docs.getmesa.com/connect/google-sheets) and select an existing Spreadsheet and Sheet. Then click the Retrieve Fields button to retrieve the columns from your spreadsheet.
## Updating columns from spreadsheet
Once you click the Retrieve Fields button, MESA will automatically add a field for each column in your spreadsheet. We use the first row of your spreadsheet as the name for each field.
Be sure to click the Retrieve Fields button in MESA after you add, rename, or move columns in your Google Sheet.
## Configuring the columns added to Google Sheets
Once your columns appear in MESA, you can use [Variables](https://docs.getmesa.com/workflow-builder/fields/variables) or text as the values for each column in the row that will be added. Variables let you pass data like Order, Product, or Customer information to the Google Sheet.
