Excel does not provide cell types the way that Spread does. Instead, Excel provides several cell formats. Excel supports cell-level data formatting by allowing format strings to be applied to cells.
There is not a simple one-to-one correspondence between Spread cell types and Excel cell formats. When Spread exports cells, Spread builds an Excel-like format string based on the cell type properties. That format string is then compared to Excel’s internal number formats. If there is a match, the format is exported as an index into Excel’s internal number format table. If, however, there is not a match, the format string is exported as a custom format.
The following table summarizes the formats that are exported when Spread exports to an Excel-formatted file and the restrictions that apply. There is a considerable amount of functionality in Spread that does not have an equivalent in Microsoft Excel and so is lost on export.
| Spread Cell Type | Excel Format | Remarks and Restrictions |
|---|---|---|
| ButtonCellType | General or Custom format | In Excel, the cell contains the value from the button cell. AllowWrap is exported for the link button. |
| CheckBoxCellType | General or Custom format | In Excel, the cell contains True or False. The check box control has no equivalent in Excel. |
| ComboBoxCellType | General or Custom format | In Excel, the cell contains the value of the selected or default item from the combo box cell and the list. AllowWrap is exported. |
| CurrencyCellType | Currency or Custom format | In Excel, the cell contains the numeric value in monetary format. |
