Microsoft Excel supports opening and saving files in many different file formats. This article contains a list of these file formats, including version numbers where applicable.


File Formats for Earlier Versions of Excel

The following table lists the supported file formats in which the entire Excel workbook is saved.
                                              File name extension
   Formats that save the entire workbook      (Windows only)

   Microsoft Excel Workbook                   .xls
   (Microsoft Excel 97-2000)

   Template (Microsoft Excel 97-2000)         .xlt

   Workspace (Microsoft Excel 97-2000)        .xlw

   Microsoft Excel 97-2000 & 5.0/95 Workbook  .xls

   Microsoft Excel 5.0/95 Workbook            .xls

   Microsoft Excel version 4.0 workbook       .xlw
   (saves only worksheets, chart sheets,
   and macro sheets)

The following table lists the supported file formats in which only the active Excel worksheet is saved.
                                             File name extension
   Formats that save only the active sheet   (Windows only)

   macro or international macro sheets)

   Microsoft Excel version 3.0 formats       .xls, .xlc, .xlm

   Microsoft Excel version 2.x formats       .xls, .xlc, .xlm

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

   WK4 (*.wk4)                 4.0             Saves the entire workbook

   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)

   .PIC (when included in      3.x and Lotus   Open but cannot save this
   an .All file)               1-2-3/W         format

Text File Formats

The following table lists the text formats that you can use to open and save files.
   Text file format                           Note

   Formatted Text (Space-delimited) (*.prn)   Lotus space-delimited format.
                                              Saves only the active sheet.

   Text (Tab-delimited) (*.txt) (Windows)     If you are saving a workbook
   Text (Macintosh)                           as a tab-delimited or comma-
   Text (OS/2 or MS-DOS)                      delimited text file for use
   CSV (comma delimited)(*.csv) (Windows)     under another operating
   CSV (Macintosh)                            system, select the
   CSV (OS/2 or MS-DOS)                       appropriate converter to
                                              ensure that tab characters,
                                              line breaks, and other
                                              characters are interpreted
                                              correctly. Saves only the
                                              active sheet.
