Have you tried this
# cat a.txt
1,2,3,WORKSTATION1\A,5
1,2,3,WORKSTATION2\B,5
1,2,3,WORKSTATION1\C,5
1,2,3,WORKSTATION1\D,5
1,2,3,WORKSTATION1\E,5
1,2,3,WORKSTATION1\F,5
1,2,3,WORKSTATION1\G,5
# sed -e 's/\\/,/g' a.txt
1,2,3,WORKSTATION1,A,5
1,2,3,WORKSTATION2,B,5
1,2,3,WORKSTATION1,C,5
1,2,3,WORKSTATION1,D,5
1,2,3,WORKSTATION1,E,5

To replace single quotes (') it's easiest to put the sed command within double quotes and escape the double quote in the replacement:
$ cat quotes.txt
I'm Alice
$ sed -e "s/'/\"/g" quotes.txt
I"m Alice
Note that the single quote is not special within double quotes, so it must not be escaped.
If, instead one wants to replace backticks (`), as the question originally mentioned, they can be used as-is within single quotes:
$ cat ticks.txt
`this is in backticks`
$ sed -e 's/`/"/g' ticks.txt
"this is in backticks"
Within double quotes, you'd need to escape the backtick with a backslash, since otherwise it starts an old-form command substitution.
