Find a way to export Acrobat Alt Text so I can spellcheck it

I need a way within Acrobat to export all the alt text from all figures. It could be an export to a .txt file. I will open it in Word and spellcheck. There is no spellcheck for alt text within Acrobat. Perhaps you know something that works. I'm not a developer or programmer. I do a lot of 508 remediateion to PDFs and alt text proofreading inside Acrobat is too time consuming (although I do it because I don't know of an alternative you may know about). Please share. Thanks.
