Conversion of tab delimited to comma delimited

I assume you can read in the file, one row at a time. Then just pass each row to a function like this, which replaces each instance of "single-quote comma" with "single-quote tab" and returns a new string. Bear in mind the data in individual fields of your data document might have commas and/or single-quotes. If so, you might need a different pattern for your regex.

        private static string ReplaceCommas(string rowData)
        {
            string pattern = "',";
            string revisedRowData = Regex.Replace(rowData, pattern, "'\t");
            return revisedRowData;
        }
