You can open Spread COM files (the current version being .SS8 files) in Spread.NET. When you do so, the file is converted into Spread.NET settings for the Spread component in your project.
To open a Spread COM file, follow the instructions for opening a Spread XML file that can be found in Managing File Operations in the Spread.NET Developer’s Guide. Designate a Spread COM file as the file to open.
Spread.NET handles borders, cell types, formulas, and other settings in several ways. Read this information thoroughly to better understand how your Spread COM file is converted into the format used in Spread.NET.
There are differences in how some default values (properties that are not set in code or in the designer) are handled between the Spread 8 SS8 files and the Spread Windows Forms XML files. Loading a default SS8 file into Spread Windows forms and saving that to an XML file will have the following default value differences from when saving to a new XML file from a default Spread Windows Forms control.The default value for the TabStripRatio property is 0.6 in the imported SS8 file and 0.5 in a new default Spread Windows Forms XML file.The default font size and character set are different with text tips (8.0 / charset 1 in the imported SS8 file vs. 8.25 / charset 0 in a new default Spread Windows Forms XML file).The default sort indicator setting is in the axis model in the imported SS8 file vs. defaulting to no sort indicator in a new default Spread Windows Forms XML file.The default cell type and font in the style model from the imported SS7 file are the text cell type and MS Sans Serif 8.0 vs. none in a new default Spread Windows Forms XML file (which defaults to the general cell type and Control.DefaultFont) .
For detailed information about equivalent members for each property, method, and event in the ActiveX control in Spread COM and how each maps to its equivalent Spread.NET member, refer to Spread COM File Member Equivalents.
