Hi,
I have translated an excel sheet which was 1 Mb and now it is 15,6. It is a weekly report form for every week of the year and so I copy pasted the first sheet onto the others. Otherwise I did not change anything, except translating the text. The file is too big like that it takes like 4 minutes to open it on a pretty good computer also. I don't know what else data is needed to find out what's happened. I tried copying it into a new file, but it stayed the same size. The sheet conatins also formulas.
