This is a sample script which works the same action with the CLEAN method of VBA. The CLEAN method of VBA removes the characters of 0-31, 127, 129, 141, 143, 144, 157
. Although I had looked for such method for Google Apps Script, I couldn't find it. So I created this. If this is useful for you, I'm glad.
function cleanForGAS(str) {
if (typeof str == "string") {
var escaped = escape(str.trim());
for (var i = 0; i <= 31; i++) {
var s = i.toString(16);
var re = new RegExp("%" + (s.length == 1 ? "0" + s : s).toUpperCase(), "g");
escaped = escaped.replace(re, "");
}
var remove = ["%7F", "%81", "%8D", "%8F", "%90", "%9D"];
remove.forEach(function(e) {
var re = new RegExp(e, "g");
escaped = escaped.replace(re, "");
});
return unescape(escaped).trim();
} else {
return str;
}
}
function main() {
var str = "###";
var res = cleanForGAS(str);
}
