Data Table to Excel numerical format



I am pulling ID numbers from an excel sheet to a data table, adding a column, then trying to move the data table back to an excel file. However, when this is done, the format of the ID numbers changes to scientific notation. Example: Numbers that begin with 0’s are having the 0’s removed, numbers that begin with larger numbers are being rounded, and all are having decimals added to them. Is there a way to properly return the ID numbers in a string format when writing the range?
