Solution 1

Try to rewrite it in this way and see what happens

C#

for (int j = 0; j < ExcelColumnCount; j++)
{
    string xmlTag = cleanedEmailTbl.Columns[j].ToString().Trim();

    XML_TRANSACTIONDETAILS.AppendFormat("<{0}>{1}</{0}>", xmlTag, cleanedEmailTbl.Rows[i][j]);
}

Let us know.

I suspect that every once in a while your xmlTag value contains one or more whitespace characters). If yu run it under the debugger, and inspect the variable when it throws the exception, you can verify my assumption.

If your table contains columns with spaces in their names, shame on you. You can change the offending column names in the table as long as you remember to change any related stored procs or in-code sql queries.
