Web Tables - 1-2-3 Millennium Edition's Web tables enable Web Design Company to send and pull useful data from any table on any HTML page of the Internet, or corporate intranet, and deliver it directly into a workbook. Stock quotes, for example, can be extracted live from a Web page and pulled into an investment portfolio spreadsheet. The Web table can be refreshed manually or automatically.

Hyperlinking - Hyperlinks can be assigned to any spreadsheet cell picture, or button. They also can be created for Internet locations, spreadsheet ranges, or objects and other files.

HTML Features - 1-2-3 Millennium Edition includes HTML 3.2 support for opening and converting spreadsheet ranges to HTML documents. Spreadsheet-specific extensions allow 1-2-3 users to share files using HTML as a common file format while preserving important spreadsheet information such as cell colors, formats, actual numbers (e.g. p = 3.14159265, not 3.14), named ranges and number formatting. Lotus 1-2-3 also offers native HTML support with XML support
