Hi guys, can anyone tell me how can I change the text case for all the notes, dims, tables present on a multy sheet drawing from lower case to upper case and vice versa?

I am working on huge draiwng update and for some reason all the text on print got changed to lower case. I want to change the text back to Upper case. Is there any command or detailing option or config option that can do this for all the text visible on drawing. Example: we can change the primary and secondary dimension from metric to inches.
