Import formula from Excel file

EasyXLS allows you to import formula from Excel file. The library permits reading Excel formula expression or the formula value.

The formula expression can be read after the Excel file is imported using ExcelCell.getValue method.

The below source code sample shows how to find the value of A6 cell that contains a formula.

External references

EasyXLS supports to build formulas that contain references to cells from other workbooks. The external reference must be an element inside a formula and looks similar to "='C:\Sample\[Excel.xlsx]Sheet1'!$A$10".

If a workbook is loaded and the workbook contains references to external documents, the external workbooks can be found using ExcelDocument.getExternalLinks method.
