Why does macro contents in Excel display incorrectly? - EeeKB

In previous sections we have known about how to use macro sheet functions to build catalogs and how to use Hyperlink functions to configue links for catalogs. 

But when I reopen it, related macro sheet functions do not work anymore... 

Since the macro sheet function GET.WORKBOOK(1) works through macro features, the documentation must be saved as this format: Excel Macro-Enabled Workbook (*.xlsm), by which the sheet catalog could display correctly during the next opening. 

Click the "Save" button on the upper right-hand corner in the Excel.

A prompt "The following features cannot be saved in macro-free workbooks" will pop up in Excel. Please click "No" to continue.

Select "Excel Macro-Enabled Workbook (*.xlsm)" file format from the dropdown box "Save as type:", and save it. 

 
Files in *.xlsm format. 

In addition, when the workbook is opened, Excel will disable macros by default. The sheet catalog could display only when clicking "Enable Content" button. 

If it does not work all the same, you are suggested to dig the Forum for any great solutions.
