Easy way to convert exec sp_executesql to a normal query?

Question

When dealing with debugging queries using Profiler and SSMS, its pretty common for me to copy a query from Profiler and test them in SSMS. Because I use parameterized sql, my q

I was looking for something similar so I use this in LinqPad, just copy sp_executesql statement to the clipboard and run the code in LinqPad. It outputs the SQL statement.

void Main()
{
    ConvertSql(System.Windows.Forms.Clipboard.GetText()).Dump();
}

private static string ConvertSql(string origSql)
{
  string tmp = origSql.Replace("''", "~~");       
  string baseSql;
  string paramTypes;
  string paramData = "";
  int i0 = tmp.IndexOf("'") + 1;
  int i1 = tmp.IndexOf("'", i0);
  if (i1 > 0)
  {
      baseSql = tmp.Substring(i0, i1 - i0); 
      i0 = tmp.IndexOf("'", i1 + 1);
      i1 = tmp.IndexOf("'", i0 + 1);
      if (i0 > 0 && i1 > 0)
      {
          paramTypes = tmp.Substring(i0 + 1, i1 - i0 - 1);
          paramData = tmp.Substring(i1 + 1);
      }
  }
  else
  {
      throw new Exception("Cannot identify SQL statement in first parameter");
  }

  baseSql = baseSql.Replace("~~", "'");  
  if (!String.IsNullOrEmpty(paramData))  
  {
      string[] paramList = paramData.Split(",".ToCharArray());
      foreach (string paramValue in paramList)
      {
          int iEq = paramValue.IndexOf("=");
          if (iEq < 0)
              continue;
          string pName = paramValue.Substring(0, iEq).Trim();
          string pVal = paramValue.Substring(iEq + 1).Trim();
          baseSql = baseSql.ReplaceWholeWord(pName, pVal);
      }
  }

  return baseSql;
}

public static class StringExtensionsMethods

   /// 

   /// Replaces the whole word.

   {
       var firstLetter = word[0];
       var sb = new StringBuilder();
       var previousWasLetterOrDigit = false;
       var i = 0;
       while (i < s.Length - word.Length + 1)
       {
           var wordFound = false;
           var c = s[i];
           if (c == firstLetter)
               if (!previousWasLetterOrDigit)
                   if (s.Substring(i, word.Length).Equals(word))
                   {
                       wordFound = true;

                               wholeWordFound = false;
                       }

                       sb.Append(wholeWordFound ? replacement : word);

                       i += word.Length;
                   }

           if (wordFound) continue;

           previousWasLetterOrDigit = Char.IsLetterOrDigit(c);
           sb.Append(c);
           i++;
       }

       if (s.Length - i > 0)
           sb.Append(s.Substring(i));

       return sb.ToString();
   }
