Rename all fields on a Form

While I realize this initial post began several years ago, I found it by accident since I presently need to rename approximately 22 form fields on an interactive PDF form I created years ago as I am in the middle of updating the form and need to rename approximately 22 form fields. Needless to say, I really don't feel like renaming every form field on the form individually as it's altogether boring and very time consuming  to say the least. However, around 18 years ago I had created a script to rename form fields while I was designing/developing interactive PDF forms for family, friends, and myself. Unfortunately, to quote an old saying, hindsight is 20/20, and I failed to save the script.  However, while I don't presently have the script, time permitting I am contemplating recreating one in JS like I had done years ago and when I am finished, I intend to post the script to the forum for others to copy/use as a way of giving back what I have learned from others over the years. This aside, getting back to creating a JS to rename existing form fields on a PDF form really isn't that difficult to achieve. In reality, if memory serves me correctly, the steps to create the JS begin with a 'for' loop whereby you essentially iterate through the form fields one by one, obtain/save the rectangular coordinates for each form field in a variable for later use, delete the old form field, and create the replacement field assigning a new name and the same rectangular coordinates you obtained/saved from the old form field you since deleted/replaced and you're done. Needles to say, all the methods used are listed and explained in the Javascript for Acrobat API Reference back then and now. Why I failed for whatever reason to save the script I created years ago to rename form fields residing on a PDF form I really don't know given the script worked like a charm. Once again, I will post the script to the forum when done as this really should have been provided by Adobe a long time ago.

Thanks for your reply. There are 3 'levels' presented there. The first 2 are out because they required Java and our IT dept does not allow java. Not sure about the 3rd
