Import & Export

SpreadJS supports the opening and saving to several popular file formats including Excel .xlsx/.xlsm, .csv, .ssjson (older SpreadJS format) and the new faster .sjs SpreadJS file formats. The new .sjs format significantly improves the load time and memory usage when working with very large Excel files while greatly reducing the file size when resaved as compared to previous SpreadJS versions.

In order to use the SpreadJS File Format feature, you need to add the related js file link into the document's head section below the Spread link. For example: SpreadJS supports opening and saving sjs file formats. It also supports importing and exporting xlsx, ssjson, and csv file formats. For example: class GC.Spread.Sheets.Workbook GC.Spread.Sheets.SaveOptions GC.Spread.Sheets.OpenOptions GC.Spread.Sheets.ImportOptions GC.Spread.Sheets.ExportOptions GC.Spread.Sheets.ImportXlsxOptions GC.Spread.Sheets.ExportXlsxOptions GC.Spread.Sheets.ImportCsvOptions .Spread.Sheets.ExportCsvOptions GC.Spread.Sheets.ImportSSJsonOptions GC.Spread.Sheets.ExportSSJsonOptions
