Question

I have a string as under

“=[Book1]Sheet1!$F$13”

The needed output being Book1

Is there any regular expression to do this?

Presently I am using string splitting to get the work done.

string input = "=[Book1]Sheet1!$F$13";
var res = input.Split('[')[1].Split(']')[0];

Thanks

If all you need is the Excel workbook’s name, this will do:

string res = null;
Match m = Regex.Match(input, @"^=\[(.+)\].+$");

if (m.Success)
{
    res = m.Groups[1].Value;
}
