The .123 extension was used by later Lotus 1-2-3 workbook generations rather than the earlier WK1 family. Anyfile asks SheetJS to recover supported worksheets, values and basic formats without running macros.

Common question
Is a .123 file plain text because its extension is numeric?
No. It is a structured Lotus workbook format; the extension is a product name reference, not a text encoding.
