File Formats for Lotus 1-2-3

When you open a .wk1 or .wk3 file in Microsoft Excel, Excel applies the formatting in the associated .fmt, .fm3, or .all file. If you save a Lotus 1-2-3 file in Microsoft Excel format, Microsoft Excel saves the spreadsheet data and formatting in a single workbook file.

The WK1 (1-2-3) (*.wk1) and WK3 (1-2-3) (*.wk3) formats save only limited worksheet formatting. To save a Microsoft Excel workbook in Lotus 1-2-3 format and retain borders, cell shading, fonts, and other formatting, select a Lotus 1-2-3 file format that stores formatting in a separate .fmt, .fm3, or .all file.

The following table lists supported Lotus 1-2-3 file formats.

   Lotus 1-2-3 file format     Version         Note

   WK3 (*.wk3)                 3.x and         Saves only worksheets and
   WK3, FM3 (*.wk3)            Lotus 1-2-3/W   chart sheets

   WK1 (*.wk1)                 2.x             Saves only the active sheet

   WK1 (FMT) (*.wk1)           1.0 and 1.0A    Saves only the active sheet
   WK1 (ALL) (*.wk1)
   WKS (FMT) (*.wks)

                                              line breaks, and other
                                              characters are interpreted
