Scripting - lifelike/countersheetsextension GitHub Wiki

There is no built-in support for scripting or any kind of expressions to calculate values in the countersheetsetension. Every value in the CSV must be known in advance and created for each counter.

This is by design and not likely to change. A CSV file is very simple to generate from any script and instead of including scripts in the extension any scripting language can be used to generate the CSV used by the extension.

This also means that it is easy for anyone with programming skills (or that can get the help from one) to use another format for counter data than the exact format used by the countersheetsextension. If it is more convenient to keep the data in INI or JSON files or just a completely different layout of spreadsheet then that can be (and has been) done. The only thing needed is a script to output the data with the headers and format required to be used by the extension before running it.
