Converting Worksheet Tables to DataTables which bind to the Data Manager results in significant performance improvements when importing Excel workbooks.

It could convert all worksheet tables to data tables which bind to the data manager by turn on the convertSheetTableToDataTable of the GC.Spread.Sheets.ImportXlsxOptions, and export to Excel file with includeBindingSource of the GC.Spread.Sheets.ExportXlsxOptions turned on. It should be known that the column based formulas will be converted when import or export, the cell based formulas will be removed when import.
window.onload = () => { let spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; async function initSpread(spread) { const loadingTip = addLoadingTip(); const tableImportExcel = document.getElementById('options-container'); await tableImportExcel.setSpread(spread); loadingTip.remove(); }
