Report Hidden Rows With An Excel VBA Macro

find hidden rows with vbaMany Excel users choose to hide a row of data on a worksheet for a variety of reasons. When Excel users collaborate it’s difficult to know that a row has been hidden without careful visual inspection of every row. If a hidden row contains zero values there is no issue. However, if a hidden row contains non-zero values it’s an issue to be concerned about.

Excel has a feature to report that rows may be hidden and then offer to unhide them. However the Excel feature does not tell us which sheets or which rows were hidden or unhidden. To use the Excel feature select the File Tab > Info > Check for Issues > Inspect Document command.

Excel’s Sum function does not ignore hidden rows, which is why Microsoft recommends we use the Subtotal function with the 109 function_number argument instead.

The subtotal function might read:

To help our students produce a report of hidden rows, Excel Class is pleased to share a program that will report if your workbooks have hidden rows. Realize that the speed at which this program operates is proportional to the number of sheets and the number of rows of data per sheet to examine. Even in a large workbook the program should finish in under 5 minutes. However, if the program appears to fail you can press and hold the Esc key on your keyboard to cancel execution.


  1. Copy the code in the courier font below into a blank new workbook, from the Option Explicit to the End Sub at the very bottom;
  2. In any Excel workbook: Hold the Alt key and tap the F11 function key to open the VB Editor.
  3. Select the Insert menu > Module command.
  4. Paste the copied code into the empty white code window.
  5. To run the program, close the VB Editor and switch back to Excel.
  6. Select the View tab of the ribbon, then click the Macros button to the far right (or choose the View Macros command).
  7. Select the FindHidden program and click the run button.

The program will prompt you to open a workbook to inspect.
