Convert an Excel table to a range of data
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.
Important: In order to convert to a range, you must have an Excel table to start with.
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.
