Parsing a CSV with unknown number of columns

[SimonHeim]

What is the recommended method to parse a CSV when the number of columns is not known at compile time?

pandas?

@wulj1 I am parsing in C++, hence my question on this repo.

I would like to open the file, count the number of columns, and then parse that number of columns. Is this possible with fast-cpp-csv-parser?

As far as I know, the column number fast-cpp-csv-parser can parsed is fixed at the compile time, you can not parse another different csv headers with a precompiled one correctly.
