Our customer reports that Excel crashes on their computer, when they attempt to open the Excel-file. I can open it just fine. However, there are a few oddities in there that I'm not familiar with.
I assume that the following J-icon is some sort of placeholder for a missing control. It seems attached to the column, so if I resize the C column, the J-icon still sits at the beginning of the D-column. If I attempt to delete all contents of the sheet without deleting the sheet itself, the icon stays. I can't select the icon itself.
Also, there are a ton of "Forms.HTML:Hidden.1" controls in one of the sheets. I've seen a lot of questions regarding this, but none explaining how they ended up there. The "Properties" window shows no properties for these controls.
I believe that removing these oddities may allow the customer to open the sheets once again.
But how do I delete them and what purpose could they serve?
The workbook was shared. Unsharing it allowed me to delete the objects.
