Getting strings from spread (from excel file)

I’m using this contribution to read excel files: However, it does not return the nr of columns and rows of the excel files. In order to get the first row, I’m trying the following:
From the spread of strings that has n slices with text followed by n empty slices followed by n slices with text (and so on), I would like to get only the first n slices of text. This should be then the first row of the excel file.

With the = (string) node, I can detect empty slices, but I can’t figure out how to extract the filled slices before the first empty slice to get the first row. Any suggestion?

Post the patch and excel file

The “select” node did the job!
