    wpforms is one of the best option for this purpose.
    I have a query about whether we would be able to make an age calculator with the help of wpforms as it is required for many educational websites for eligibility purposes?

    Looking for a plugin I can use to drop any excel calculator into a post. Without bringing in the entire file, all the extra blank cells etc. I make them myself. Don’t need someone to do that. But I need to be able to drop them in and make them work.
