I use data that is export from electrical test equipment in CSV
format. For years I have been developing vba code to manipulate this
data for analysis. One problem with the data is that it is grouped in
columns in a way that makes analysis and charting cumbersome. I
should have worked this out long ago but must have enjoyed the
struggle.

the data come in in columns like:
TYPE, DATE, DC_RES, IMP_100_Hz, PHASE_100_Hz, LC_100_Hz, QD_100_Hz,
IMP_200_Hz, PHASE_200_Hz, LC_200_Hz, QD_200_Hz, IMP_400_Hz,
PHASE_400_Hz, LC_400_Hz, QD_400_Hz, IMP_1_kHz, PHASE_1_kHz, LC_1_kHz,
QD_1_kHz
The data runs higher in frequency

I need to reorganize the data so that each data type is grouped
together. For instance TYPE, DATE, DC_RES, IMP_100_Hz, IMP_200_Hz,
IMP_400_Hz, IMP_1_kHz, etc

a push towards efficient way to do this would be helpful.
thanks
