Hi Fernanda658,
I'm Femi and I'd be happy to help you with your question.
To import a spreadsheet as a new tab in an existing spreadsheet, you can follow these steps:
Open the existing spreadsheet where you want to import the new data.
Click on the "File" menu in the top-left corner and select "Import."
In the "Import" dialog box, select the "Upload" tab.
Click on the "Select a file from your device" button and choose the spreadsheet file you want to import.
Select the option "Replace current sheet" if you want to replace the current sheet with the imported data, or select "Import data" if you want to add a new sheet with the imported data.
Choose the format of the data you want to import, such as "Excel" or "CSV."
Click the "Import data" button to import the spreadsheet as a new tab in your existing spreadsheet.
After following these steps, the new spreadsheet data will be imported and displayed as a new tab in your existing spreadsheet.
Best Regards,
Femi
