Large-Scale PDF to Word Conversion

I have a substantial PDF file, well over 100 pages, that I need to convert to a Word document. The primary objective of this conversion to Word is for editability. I need to be able to easily make changes and edits to the content. The requirement is for basic formatting, retaining elements like headings and bullet points. Extensive experience with both PDFs and Word and keen attention to detail will be beneficial for this task. Proficiency in converting PDF to Word while maintaining basic formatting is ideal.
