Start with the DOCX, save the converted PDF, and open that saved copy to check it. This walkthrough uses a sample community garden plan with a list and a table. The last part checks the PDF in a viewer and opens its heading bookmarks.
Converting is only the first step. Before sharing a document, look at the page breaks, table edges and text in the file you actually downloaded. The sample document was made for this walkthrough and contains no private information.
