# Performance Metrics for Excel to PDF Conversion

The following benchmark demonstrates the performance of the Syncfusion Excel (XlsIO) library when converting a large Excel workbook—containing 100,000 rows and 50 columns with distinct data types such as text, date and time, numbers, booleans, and formulas—into a PDF.

Conditional formatting allows to format the contents of a cell dynamically. This can be defined and applied in XlsIO through the [IConditionalFormat](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IConditionalFormat.html) interface.
