[Eug-Mart]

I am using NPOI (v2.7.1) to work with an Excel file that contains a formula using XLOOKUP along with other functions like IF. While the XLOOKUP support was introduced in PR #815, when I attempt to evaluate the formula using FormulaEvaluator.EvaluateFormulaCell(cell), it returns the formula instead of the calculated value. I would appreciate any suggestions on resolving this issue or confirming if there's a problem with XLOOKUP implementation in NPOI.
