After you create an Excel table, you may only want the table style without the table functionality. To stop working with your data in a table without losing any table style formatting that you applied, you can convert the table to a regular range of data on the worksheet.
To successfully complete this procedure, you must have first created an Excel table. For more information, see Create or delete an Excel table.
You cannot convert a table to a data range in Excel Online.
Click anywhere in the table then go to Table Tools > Design on the Ribbon. On a Mac go to the Table tab.
In the Tools group, click Convert to Range.
Right-click the table, then in the shortcut menu, click Table > Convert to Range.
Note: Table features are no longer available after you convert the table back to a range. For example, the row headers no longer include the sort and filter arrows, and structured references (references that use table names) that were used in formulas turn into regular cell references.
