How to add "from Csv"-Button when creating SharePoint Lists?

Hi Gordon35,

The "From CSV" button when creating SharePoint lists is a feature that is still in preview. It is not yet available to all tenants.

To check if the feature is available to you, you can try the following:

1. Go to the SharePoint Online site where you want to create the new list.
2. Click the + button to create a new list.
3. Under Create a list, click From existing list.
4. In the Select a list dialog box, click Import from CSV.

If you do not see the "Import from CSV" option, then the feature is not yet available to you.

To request access to the preview feature, you can contact Microsoft support.

If you need to create a list from a CSV file now, you can use a workaround:

1. Create a blank list.
2. Click the Export to CSV button.
3. Open the CSV file in Excel.
4. Add your data to the CSV file.
5. Save the CSV file.
6. Click the Import from CSV button.
7. Select the CSV file that you created.
8. Click Next.
9. Map the columns in the CSV file to the columns in the list.
10. Click Import.

This will create a new list with the data from the CSV file.
