When you use Excel to prompt stdole32.tlb to be lost or damaged, it is possible that there is no stdole32.tlb file in your computer, check to see if there is stdole32.tlb file under the directory C:windowssystem32 first.
If you do not have stdole32.tlb files, you can download a stdole32.tlb file on the Web to the directory c:windowssystem32, and then use Excel to see if there will be error prompts. If you have this file, replace the downloaded file with the original Stdole32.tlb file.
You can also copy a stdole32.tlb file on your colleague's or friend's computer c:windowssystem32 under the C:windowssystem32 directory on your computer or replace the original stdole32.tlb. The premise is that the copied computer also has the same version of the Excel program.
If none of the above fixes the problem, you only have to reload the Microsoft Excel program, which is to reload the Microsoft Office program. Download a Microsoft Office program installation package from the Internet, Baidu Search will be able to find a lot.
