Its

formulaString.replace("\'", "\\\'");

The odd part was that since \ is special too, it must also be escaped.

or

formulaString.replace(R"(')", R"(\')");

which use the new raw strings and is good if many chars that need escaping.

formulaString.replace(R"(')", R"(\')");

When you need to have a special character in string you have to prepend with a backslash as you know obviously already. The confusion comes typically because backslash is also such a character.

formulaString.replace("\'", "\\\'");

The examples of [QRegularExpressions](formulaString.replace("'", "\'") and playing a bit may help.
