Linux - Convert Excel (XLSX) File To CSV
Today I received a 3.9 MiB Excel file with over 120,000 rows and I needed to convert it to a plain CSV file quickly so I could easily work with it programmatically. Unfortunately, trying to do this with a LibreCalc operation was taking forever, and I found this alternative that does the job in just a few seconds.
Install gnumeric if you haven't got it already:
sudo apt install gnumeric
Run the following command:
ssconvert input.xlsx output.csv
