Ability Spreadsheet
Ability Spreadsheet (AWS for documents, AST for templates) is the native format of the Spreadsheet program in the Ability Office suite, though this program also supports some other, more widely-used formats.
Templates appear to be in a similar format to documents, though slightly larger.
Current versions of Ability Spreadsheet can read and write files of the current 6.x format and earlier 4.x and 1.5 formats.
In the 6.x format, the characters of text within the spreadsheet appear to be in a 16-bit encoding, little-endian; probably 16-bit Unicode or UTF-16 (ASCII characters show up as their normal values with extra 00 bytes between them to fill out the 16 bits). This is similar to Ability Write. The 4.x format (as with Ability Write) seems to store only ASCII, in 8 bits. However, oddly, the 1.5 format (as seen when you save a file that way in the current program) seems to have 16-bit Unicode, meaning they perhaps started that way, reverted to ASCII, then resumed Unicode use later. Or else the 1.5 save format doesn't work correctly and the files won't really work in that old version.

Identification
Files appear to begin with the hex bytes D0 CF 11 E0 A1 B1 1A E1. However, so do files in Ability Write, so you can't easily tell the difference other than by file extension.
