Today I did my first advanced spreadsheet on LibreOffice after switching to Linux, and it handled itself pretty well. I had to search for some features on the web at first, but after I got it down, I felt comfortable using it. Also, LibreOffice’s default menu layout is not pretty, but I can find all of the functions with just a click, unlike MS Office’s ribbon menu where I had to click around to find what I was looking for. Sorry for bad English.
I do a lot of work with CSV files and LibreCalc is so much better for them. You can actually tell it how to delimit the file and to put quotations around each field.
Some programs actually advise against using excel if you’re going to work on a CSV to upload into the program, which is funny considering it’s meant to be the industry standard.
P. S. For anyone that would like to use LibreOffice at work, download portableapps and get it from there. It’s so portable it can get around IT administration requirements
I agree with LibreCalc and CSV, in some internationalclasses we always had issues with excel saving CSV in actually different formats depending on the machine locale. LibreCalc never had this problem.
