Not sure if this is a bug or feature, but I am sure it's an edge case...
1. Enter some text in Microsoft Excel, like an empty cell with "test".
2. Paste text in POP Peeper, with CTLR + V (keep style) or CTRL + SHIFT + V (plain data).
3. The text from the cell is pasted.
So far, so good. But the thing is with step 2 that POP Keeper is always trying to paste the textual data as an image, even with CTRL + SHIFT + V, which should "delete" the image wrapper around the copied data, and only paste the textual data.
You can "cancel" the option to paste the data as an image, but I think (when using CTRL + SHIFT + V) it should not be an image in the first place?
Ok, to back things up a little:
1) I wasn't aware that Ctrl+Shift+V was "official" -- I was surprised when it actually did something (ie. paste)
2) Google AI tells me this was added in March 2023. But another search tells me that "Microsoft is also working to make the shortcut available system-wide through its PowerToys program" -- I use PowerToys so maybe that's why it works. (I see it in powertoys but it's Win+Ctrl+Alt+V). This is a rabbit hole I'm going to stop exploring now.
3) The editor that POP Peeper uses supports Rich Text (e.g. bold, etc.) but since POP Peeper itself doesn't currently support the ability to send marked up text, it forces everything to plain text when you paste.
So, as far as PP is concerned, it has special code to include an image that's on the clipboard as an attachment. The primary use of this being to quickly add screenshots. (similar but different, you can also "copy" file(s) from FileExplorer and then "paste" them to include them as attachments).
When you copy from a spreadsheet, it appears to copy an image and the text to the clipboard. I'd say this is slightly unusual; or at least I haven't come across it before.
I'll add this to my notes to look into, but I'm not sure that PP can tell the distinction as to whether you "pasted" or "pasted plain text".
In the meantime --
I don't have excel, but I have the equivalent LibreOffice Calc which behaves similarly as to what you've described. If you copy the text of the cell instead of copying the cell itself, PP will only paste the text and not prompt about the image. Not sure that's any easier than just pressing <esc> though...
As far as I can tell -- after some research -- there's no way for the app to tell which keyboard shortcut you used to paste. Unfortunately, there's not much (well, *any*) documentation about it, so it's probably too new for it to come up.
However, I think I will change PP so that it favors text over the image; after all, there already is a menu option to paste the image from the clipboard in that case (and I should consider moving that menu item from "Options" to "Edit").
