Hello, I'm trying to export the data from a FFT I've done in LTSpice so I can plot it in Excel to make a prettier graph. Unfortunately the files have too many values in for Excel to handle, any ideas on how to reduce this length?
Cheers,
Steve

Hi,
Try joining the LTSpice user's group here. In the files section, Helmut Sennewald has uploaded a utility that allows you to pull out pieces of the LTSpice output data files and export them as text. I've used this in the past to get data out of LTSpice. It's pretty tedious but it works. Though there is some text in the output files, these are actually binary last I checked. It helps to turn off all file saving in the LTSpice control panel, then use the .SAVE directive directly in the LTSpice schematic with only the variables for which you want saved data.

Hi andy,
I've already exported as a text anyway, in a form that I can get in Excel. The only problem was that there was too many values to fit into an excel spreadsheet, as the freq increments were too small. Anyway all is well now, as I was having a funny 5mins thinking that 20000 was equal to 2x10^5 not 2x10^4 😱 how embaressing!! But now the number of values is small enough to fit in windows, which is nice 🙂
