Case conversion is not as easy as it may seem.
If your letters are from the A-Z range, all is fine and you can use Jim's solution.

For other languages than English there may be more letters to translate, e.g., German has the umlauts ÄÖÜäöü. These are outside the A-Z range of the ASCII table. So you need a translation table suited for the language the text is in.

Timo Salmi's TSFLTB (download) includes sample filters for case conversion.

Usage is:
FILTXT.EXE INPUT.TXT OUTPUT.TXT LOWER.XLT
or
FILTXT.EXE INPUT.TXT OUTPUT.TXT UPPER.XLT

Unfortunately this tool suffers from the well-known Runtime Error 200 bug, so you have to run a fix. It works fine with Veit Kannegießer's R200FIX, which you can find at https://kannegieser.net/veit/programm/index_e.htm. This is a TSR, so you have load it again after rebooting your machine. Either include it in your AUTOEXEC.BAT or have a look at fixes patching the EXE file: FREE SOFTWARE FOR DOS — System Utilities
