I have a big dataset in excel which I would like to copy to a latex document. I've tried it using https://www.tablesgenerator.com/latex_tables#. Unfortunately, when I tried to paste the latex-version of the dataset into latex (online version), I got a message telling me that I should upload a file directly to latex instead because direct copying from copyboard to latex doesn't work. Do you have any suggestions how to deal with it? Is it somehow possible to export the output from https://www.tablesgenerator.com/latex_tables# into a file that latex can read?

Many thanks in advance for your support.

Best,
