+
+## Description
+This article demonstrates how to deal with formatting difficulties when exporting an XLSX file to PDF using the RadSpreadProcessing library in .NET Standard. 
+
+The most common scenario is:
+1. Export an XLSX file to PDF using the RadSpreadProcessing library.
+2. Observe the resulting PDF file with truncated columns or different font.
+
+## Solution
+The limitations of .NET Standard may cause differences in font and text size (text measuring) when converting to PDF format.
+
+1.To address the issue with the size discrepancy, set a `SpreadFixedTextMeasurer` to handle the problem with the size:
+```csharp
+SpreadTextMeasurerBase fixedTextMeasurer = new SpreadFixedTextMeasurer();
+SpreadExtensibilityManager.TextMeasurer = fixedTextMeasurer;
+```
+
+2. Implement a `FontsProvider` to handle differences in fonts. This class provides a mechanism to read the fonts used in the document:
+```csharp
+public class FontsProvider : Telerik.Windows.Documents.Extensibility.FontsProviderBase
+{
+    public override byte[] GetFontData(Telerik.Windows.Documents.Core.Fonts.FontProperties fontProperties)
+    {
+        //...implementation details...
+    }
+}
+```
+
+3. Update the `FontsProvider` implementation to include the necessary fonts and their corresponding font files.
+
+Please refer to the attached sample project for a complete implementation. Test the solution on your end to verify if it resolves the formatting issue.
+
+## Notes
+It is important to note that the limitations of .NET Standard may still result in slight differences in font and text size when converting to PDF format.
