Dear PaulMarsh9414,
Greetings! Thank you for posting in Microsoft forum.
May I know how you are planning to export Word content to Excel? There are two methods that I can think of:
- Save As word document as Plain Text and then in Excel, click Data > From Text, and in Import Text File dialog, select the text file you want to import.
- Copying data from Word document and pasting to Excel workbook.
The option # 1 can help you import data but there are chances that all the data from Word might not come to Excel and I am afraid that data in text box may not import to Excel at all, the safer option would be option # 2.
If your main concern is “the word doc is HUGE and takes forever to consume when stored in SharePoint DL. I worry the docx is going to become so corrupt the content is unrecoverable”, may I know how big the document is? According to the support article, the maximum file upload size is 250 GB, the file this big can take a lot of time depending on your network connection/speed. If you still worry, you can consider, copying the content to multiple documents to make it smaller in size and as a backup, save one copy to your local computer.
Besides, please note when creating a SharePoint list from Excel, there are some limitations:
- If the spreadsheet file you're importing doesn't have a table in it, follow the on-screen instructions to create a table in Excel, and then import the table to your list. If you get stuck creating a table, search for "Format as Table" at the top of your file in Excel.
- Some Excel data types cannot be exported to a list on the SharePoint site. When unsupported data types are exported, these data types are converted to data types that are compatible with SharePoint lists.
Refer: Create a list based on a spreadsheet (microsoft.com)

If you need any help, let me know, I will be happy to assist further. We will look forward to your reply. Stay safe and stay healthy.
