+# How are spaces in cell values handled by XlsIO during calculation?
+
+In Microsoft Excel, leading and trailing spaces in cell values are preserved for display purposes. However, when performing calculations (for example, **=A1+5** where A1 contains **" 25 "** with spaces), Excel automatically ignores those spaces and treats the underlying numeric value. Spaces are always shown in the cell but ignored in calculations. Syncfusion XlsIO follows the same behavior.
