python - split dataframe into multiple dataframes based on number of rows - Stack Overflow
Awesome example that shows how to split a CSV into groups / chunks of 10 and to write them into files (CSVs) complete with header. In other words, if you have a large CSV file, you can chunk it into files with this approach. Works for read_excel and to_excel as well.
