You don't need Excel to calculate values in Word. Just drop your values into a table, insert the right formulas, and you're done!

In Word, you can perform logical comparisons in a table using formulas. A formula in Word updates automatically when you open the document that contains the formula.

If you store values and formulas in a Word form field, Word can apply a data type to the data rather than interpreting everything as normal text. Form fields can store static values and formulas.
