Numbers can't save changes to Excel files but can export Excel files?
I have an Excel file someone sent me. I made some modifications to it and tried to save the file, but it started asking me where I wanted to save the file for some reason. Picking a location creates a new file in the Numbers format for some reason. It made me think it may not be possible to create or save Excel files in Numbers, but it IS possible. But you have to create a NEW Excel file every time you make changes for some reason. You do this by exporting whatever file you're working with as an Excel file (i.e. exporting an Excel file as an Excel file...???). Is it possible to just save the file I'm working with without these unnecessary extra steps? This is highly cumbersome and I can't fathom a technical excuse to justify this.
