Is there a preview plugin that would allow me to enter data into Excel cells directly in the preview window? (Or text into a Word doc etc.)
Not that I know of. Or not that you would want to use, at least. There is the legacy option of running Excel and Word themselves in the viewer pane but it doesn’t work very well these days and is not recommended compared to the modern Office preview handlers.
Ok, thanks!
Your post served as a hint to me. I went on trying installing office 2003 and chose legacy option for excel file preview. Here is what I got:
I like the way it enabling editting, but I couldn't find a way to save what I have inputted into the file.
Is there some workaround to achieve this ?
There isn’t a good way because the Excel preview handler is read-only.
Using the legacy method of hosting Excel itself in the viewer pane isn’t recommended. That is for 16 year old versions of Office, and brings with it many issues. We may remove it as it should never be used these days.
Okay, but please don't remove it, more versatile options can't be a bad thing.
The legacy option is nothing but pain. It isn't worth it, trust me. If you want to edit an Excel document, open it in Excel.
