unable to paste text on excel

[tiago.gp.pythium]

hi there, i'm working on an excel spreadsheet, and basically i have to copy text from a pdf file to an excel sheet.
sometimes, without doing anything different i stop being able to paste, on the cell or on the formula cell (i've been pasting there because of different formatings in the text).
i have no idea how to resolve this. i close the spreadsheet, i open a new one and try to start over and the same thing happens.

i'm working on a macbook, and it's excel 15.13.3, don't know if this matters. if i haven't explained myself correctly ask away. thanks

Excel issues can be a pain at times, check your plug-ins and disable all of them. I have seen this issue happen with some plug-ins, as well as corrupt sheets or even corrupt cells within a sheet. Also try creating a new sheet but use an older (or newer) Excel sheet version.
