Yet Another Number-To-Words Function (Sorry, US Style Only)
You are probably wondering, "Why on earth is he posting another number-to-words function?" Well, I think mine is slightly different than those you have seen before. For one thing, my function can handle very large numbers... a fraction less than a quintillion. That is a number with 18 digits in front of the decimal point! For another thing, you can post your output in any one of four different way. Anyway, follow these instructions and try it out... if you don't like it, you can always delete it.:closeeyes: And, of course, this function can be called from your other VB code or it can be used as a UDF (user defined function) in worksheet formulas.
Go into the VB Editor (Alt+F11) and add a Module to the Workbook (Insert/Module from the VBA menu) and then paste in all of the code appearing below into the Module's code window. You can call the function from your work sheet like this =NumberAsText(A1) where A1 is assumed to hold the number you want to convert. There is an Optional argument you can use to format the results to your liking. Here are some examples to show the options available...
A1: 123.45
In B1:
--------------
=NumberAsText(A1) ==> One Hundred Twenty Three Point Four Five
=NumberAsText(A1,"And") ==> One Hundred and Twenty Three Point Four Five
=NumberAsText(A1,"Check") ==> One Hundred Twenty Three and 45/100
=NumberAsText(A1,"Dollar") ==> One Hundred Twenty Three Dollars and Forty Five Cents
=NumberAsText(A1,"CheckDollar") ==> One Hundred Twenty Three Dollars and 45/100
To summarize, using "And" adds the word "and" in front of the tens/units text; using "Check" formats any decimal values as would be written on a check; using "Dollar" adds the words "Dollars" and "Cents" in their appropriate positions; and using "CheckDollar" adds the word "Dollars" but leaves the decimal portions as a fraction of a dollar.
The code is laid out in a reasonably straight forward manner, so if Dollars/Cents is not you native currency designation, you might be able to modify the program to fit your own units. In addition to the above, for all modes, the Plus and Minus sign can be used and will be reported back as a word; commas may be used to separate the numbers to the left of the decimal point but they will not be reported back by the routine and are permitted for the users convenience (however, if commas are used, they must be placed in their correct positions). If you specify an option that includes words, those words are properly pluralize (meaning 1 reports as One Dollar and not One Dollars). And, as I said earlier, this function will work with a whole number part up to one less than a quintillion (you can have as many decimal places after the decimal point as desired), but remember to pass in very large numbers as Text... otherwise they will end up being converted to Doubles (which will destroy the conversion).

HOW TO INSTALL UDFs
------------------------------------
If you are new to UDFs, they are easy to install and use. To install it, simply press ALT+F11 to go into the VB editor and, once there, click Insert/Module on its menu bar, then copy/paste the above code into the code window that just opened up. That's it.... you are done. You can now use NumberAsText just like it was a built-in Excel function. For example,
=NumberAsText(A1)
If you are using XL2007 or above, make sure you save your file as an "Excel Macro-Enabled Workbook (*.xlsm) and answer the "do you want to enable macros" question as "yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.
Your help is much appreciated
what if I have 123.20 and convert it into *** ONE HUNDRED TWENTY-THREE AND 20/100 PESOS ONLY ***,
Thank you for your effort in helping us..
