Understanding the Netscape HTML Format
Browser bookmark backups use the 1990s Netscape Bookmark Format: nested <DT><A HREF="..."> tags with ADD_DATE timestamps. Spreadsheets cannot parse this structure natively without conversion into rows and columns.
The Automated Conversion Workflow
You can convert bookmarks by running a 10-line Python BeautifulSoup script extracting href, text, and folder headings, or by importing the HTML file into Marqly and clicking “Export to CSV” to get columns for Title, URL, Tags, and Date Added.
