Helllo, i am currently working with dagster to parse a really long excel file, my startegy involves read a line and execute a pipeline with the data from that line, seems a not so good way to do things. I would like to run it just once, can someone give me a opinion on how to accomplish that. Thanks in advance.

It depends on what you are trying to do exactly, but I would look at something like Pandas (https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_excel.html).
