I added some extensions for your excellent packet.

If you take those extensions to your code, then I'll remove my version. I have no need to offer other versions.

• csv headerlines handling, headerline writing
• template Format support added
• CSV column separator option
• Excel formula support in template and in csv, csv formula overwrite template formulas
• debug option
• verbose option, show rownumber - processin g ....
• startrow option, which csv line is first to read
• more command line options, I use global param struct, not so nice, someone could fix nicer. I'm so Go beginner ...
• also footer template ex. including sum column
• environment variable extension

@DeyV Do you have an idea for the number to string formatting?
A small number is okay but a long number such as '1114012700100530002020472' is formatting as exponential numbers.
I just want to change all fields to string with any data.

Probably You can type an apostrophe (') in front of the number, and Excel will treat it as text.
