openpyxl load_workbook() freezes

Question

I'm trying to use wb = load_workbook(filename) but either I work in Python console or call it from a script, it hangs for a while, then my laptop completely freezes. I can't switch to console to reboot, can't restart X etc. (UPD: CPU consumption is 100% in this moment, memory consump. is 5% only). Has anybody met such issue?

Python 2.7, openpyxl 2.4.9

Answer 1

The warning is exactly that, a warning about some aspect of the file being removed. But it has nothing to do with the rest of the question. I suspect you are running out of memory. How much memory is openpyxl using when the laptop freezes?

Answer 2

I had this issue kinda.... I had been editing my excel workbook. I ended up accidentally pasting a space into an almost infinite amount of rows. ya know... like a lot. I selected all empty cells and hit delete, saved workbook, problem gone.
