MS Excel is a highly advanced spreadsheet application which allows you to organize, store and manipulate data in a efficient way. It also lets you implement VBA and generate custom solutions. For naming VBA modules you have to strictly follow the conventions used for naming. Your failure in doing so, may result in different types of error with the VBA modules like excel invalid data format and other similar messages.

Let us consider a practical scenario in which you are trying to implement certain tasks and all of a sudden encounter “Invalid data error” with the occurrence of following message:

[Open] or [Excel workbook closes. Run VBA macro. Remove VBA modules. You can export the VBA Editor module. VBA please edit the text in the module.

          

Causes:

Excel invalid data format error generally occurs if you are trying to add reference to add-in file which does not possess Visual Basic module. You may encounter this error while opening an Excel workbook, running VBA macros, removing VBA module, exporting VBA module in editor, editing text in VBA module and accessing Visual Basic Editor. You may also face this error if you are using a VBA module which has been named as “dir” or “Dir”. As these names are reserved for specific modules, so if they are used for naming VBA module it will throw error messages to you. Another most common reason responsible for this error is corrupted Excel workbook.

Resolution:

In order to resolve Excel invalid data format issues, you have to open the workbook and entire content should be copied to another workbook having a different name. After that you can easily delete the damaged workbook. In case you are not facing the problem due to incorrect module naming, you should repair the corrupted workbook. For doing this open the damaged file with 'Open and Repair' feature.

However if all these methods fails and you are still facing the same problem you can take the help of third-party Excel repair applications. These third-party utilities are especially designed to fix all types of common Excel errors including Invalid data format error and efficiently repair corrupted Excel files.
