A common situation for us (people in the programming/computing/processing world) is that we don’t always work with the same tools as some of our non-tech peers.
Case in point, I received a big bunch of files in XLS/XLSX format, very big files, LibreOffice has trouble working with them. Since I want to perform quick processing on that data, and I already have scripts that process similar data in CSV, the simplest path is to transform those files to plain, ugly, useful CSV files.
Then again, there are 100 files, and I don’t feel like dancing around each one: opening, clicking save as, selecting CSV, telling LibreOffice that this is a semicolon separated CSV file … etc etc.
