I don't understand why I can't open these lists in your saved format. For me, using the pdf format is common, but in this situation, it does not work for me. I am a high school teacher and I have been tasked with compiling lists of students who have passed exams this year. I used the service https://pdfliner.com/proof_of_vaccination_form
to convert the document to pdf and edit it. I can say that in this format it is much easier to work and highlight the necessary information. In the future, I plan to completely switch to documentation in this format.
