2 columns of spreadsheet data into indicator and into an FFT

Solved!

Great  catch of this hiiden typo.  now the spreadsheet  works well for 2 columns.

 

Do you have any idea for linking the 'spreadsheet read vi'  to the input of the 'amplitude spectrum vi' without the 'real world vi' that is in there now ?

Use index array to get a given column.  Then you need to build that into a waveform so you can define the dT value that is the time between consecutive values.

 

Then you can wire the waveform into the FFT.
