Generating Spectral Data

How do I generate spectral data in ColourSpace similar to .ccss files? But in ColourSpace file format .edr or .csv?

Sorry, but you currently can't. You need specialist spectrometric software. I believe there are plans to have CS work directly with spectral data eventually, but it isn't now.

I don't plan on using spectral data in ColourSpace. I wanted to use it here......

To see how well the generated AWP does to match Reference tech. DisplayCal can generate spectral data. But sad to hear that ColourSpace can't.

Unfortunately, due to the underlying issues with metameric failure, trying to use spectral data to generate an alternative white point is basically a useless procedure.
While very narrow bandwidth spectros can potentially generate more accurate readings, they will not correct for the underlying metamerism that causes metameric failure.
The only way to generate alternative white points that actually works is via a Perceptual Match.
