I'm a new user of ubuntu. We are 4 in the ooffice and and 3 of my work mates are using ubuntu. My laptop is the only one that has a windows 7 installed. This week, when I used their computer and make an excel report using the Libre Office calculator, I like how it works. However, when I opened it in my laptop, it says :" Excel found unreadable in "name of file". Do you want to recover the contents of this workbook? if you trust the source, click yes. "
This is how the message appears and when I try to click yes, it will open but the file is not the same as what it should be. I tried to save the file with the type: "Microsoft Office Excel 97-2003 Worksheet (.xls)" but still it doesn't works. On the other hand, the excels files from windows 7 works well if I open in ubuntu.
Would somebody help me please? I tried to search in forums what to do but I couldn't find a good answers and sometimes their are but could not understand a lot since I'm not really good in understanding the commands in computer. I tried to upload the file here as attachment but it says the file is invalid... .. I run out of ideas already on what to do..
