# Does XlsIO support auto-correcting formulas?

No, Syncfusion XlsIO does not support auto-correcting or recalculating formulas automatically when loading Excel files. To resolve this, open and resave the Excel file using Microsoft Excel. This triggers formula evaluation and updates the cached results. Once resaved, XlsIO can process the file and return the correct values.

Alternatively, invoke the <a href="https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html#Syncfusion_XlsIO_IWorksheet_Calculate">Calculate</a> method of <a href="https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html">IWorksheet</a> to evaluate and update all formulas in the worksheet.

Use the <a href="https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html#Syncfusion_XlsIO_IWorksheet_EnableSheetCalculations">EnableSheetCalculations</a> method of <a href="https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html">IWorksheet</a> to initialize <a href="https://help.syncfusion.com/document-processing/excel/excel-library/net/working-with-formulas#calculation-engine">CalcEngine</a> objects and retrieve calculated values of formulas in a worksheet. On completion of worksheet calculation, invoke the <a href="https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html#Syncfusion_XlsIO_IWorksheet_DisableSheetCalculations">DisableSheetCalculations</a> method of <a href="https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html">IWorksheet</a> to dispose all <a href="https://help.syncfusion.com/document-processing/excel/excel-library/net/working-with-formulas#calculation-engine">CalcEngine</a> objects.
