Update a table from a SharePoint list
You can periodically update your Excel worksheet with changes from the list.
IMPORTANT: When you refresh the data in your worksheet, you’ll be overwriting any changes you might have made to the worksheet after your last export.
Click anywhere in the table that you want to update.
Click Design >Refresh.
NOTE: Though you can’t update any changes from your Excel worksheet to an existing SharePoint list, you can export the changed table as a new list with a different name.
Unlink a table from a SharePoint list
If you no longer want a connection between the table data on the worksheet and the SharePoint list, unlink the table by clicking anywhere in the table, and then clicking Design > Unlink.
