For MS Win people :)
This is an MS Excel based fonts editor-converter for Adafruit, UTFT, Squix' V2/V3 C arrays and binary formats.
It can also read/edit/write Adobe BDF format and convert between it and all above.

It can be used to edit Squix project fonts like Metocons and 7SEG etc.
Note, it may take long time for Excel itself to open and display first time "large" fonts!
