I think my recent changes to csv2xlsx warrants an update.

As this is on github but not yet released, feel free to comment on the new -S/--split feature, so I can update the docs or amend the code.

To explain the new options: I was faced with a 50_000 line CSV file that had logical vertical sections. The section start was clearly marked. Say you have a CSV file with orders per customer, grouped by customer, and every such section starts with Customer,34526,"Foo Tool Factory",20220601,... followed by the orders.

What I wanted was to convert this CSV to Excel (as required by the other end) where each customer had its own sheet. With the new options that would be:

$ csv2xlsx -S A=Customer --sl=C orders.csv
[download]

Start a new sheet when column A is "Customer" and then use the value in column C for the matching record as label for the sheet.

-S (or --split) also supports syntax for regex/empty/undef/compare and can be stacked.
