The file seems to be corrupted. For example line 1970 has too many entries and starts with a date that is out of sequence. Line 22693 also has too many entries.

I'd take another look at how you generated the file, or at the source data, as it's obviously not working quite as you expected.

Edited to add

A quick way to find this sort of problem is to open the EPW in Excel, do Data > Text to Columns on the time series part of the data, then Ctrl-down to find any discontinuities - either gaps within the expected data area or extra values beyond it.

How to deal with (syntactical) errors in self-created weather files such as the example above is shown here

Hey, now I fixed the problem with the time-data. Just the months january and December – not an entire jear, hope that this is OK (because I want to simulate just this 2 months). I can open the file in elements. I can copy the Temperature – everything works.But if I try to copy relative humidity etc. it does not work – just empty cells. I can’t copy the data in excel into the epw file – if I try: I can’t open the file in elements/Eplus. It would be so great if someone could have a look at this - I need to finish a paper and the only thing that does not work is to import that measured climate data :/.

thank you very much!
