Hi kalavinod,
I don't have 123 here at work. However, I seem to recall... If you format the entire sheet as TEXT, 123 will display the formulas. You might also have to adjust the width of the columns to display the entire formulas.
Save the file first, BEFORE you format as TEXT and change the column widths. Then you only have to open the file to revert back to your normal formatting.
I hope this helps.
