It's not the same thing at all. That's just the way different programs display data and has nothing to do with compression. I don't mean to sound rude but it's unrelated to the point being discussed here.JamesMellor said:I agree , but save an excel file and open it in works or word , its all there but over four pages , open it in numbers and its all there but at an 80% page size when printed, open a word file in pages fill it in save it and open it in word the forumilas dont work and everything is xxxx's.
After that try open office.
The data can be presented differently
If you compress an Excel file to a ZIP file then uncompress the ZIP file back again, when you open the uncompressed file in Excel it will still be exactly the same even though it's been through a compression/uncompression process.
