Unsupported file format, Wyko .asc

I’m trying to upload a Bruker (Wyko) .ascii / .asc file but it keeps getting rejected as an unsupported file format.
The header and first 5 lines of data reads:

Wyko ASCII Data File Format 2,1,1
X Size,640
Y Size,480
Block Name,Type,Length,Value
Wavelength,7,4,75.594002

0.000000,0.001974,-5965.671387

I’ve tried uploading this as is with comma separation and tab instead of comma but neither work.
Is this file format incorrect or am I missing something fundamental?
