Tab separated value import issue with header in file

GregM

I have years worth of data saved as tab separated values, unfortunately, each file also has the following header, that I can not figure out how to work with.  No matter what I have tried I can not get the following rows of data to import, it always gives an error of:  "an attribute is specified for column 1 but column 1 does not exist" and fails to recognize the dozens of columns of data below the header.  Manually removing the header enables the import wizard to work properly, but removing that manually is not really an option for thousands of datafiles.

Anyone have a good idea how to get past this issue?  I was planning on looping through the files in the folder structure, extracting the unit SN,PN, Date,Time from either the header or the file name, and combining it all together into one set of data to look at the population over time, but I am stuck at ostensibly the simplest part of the whole thing, how to automate the import of the text file.

Hi,

there is no possibility to deal with headers out of the box, but there is a workaround consisting of several operators. Please have a look at the process below for an example, and be sure to set the last_example parameter of Filter Example Range to the number of header lines in your files.

Best regards,
Marius
