 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.
+1. [Export an XLSX file to PDF]({%slug radspreadprocessing-formats-and-conversion-pdf-pdfformatprovider%}) 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;
+        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:

+        FontsProviderBase fontsProvider = new FontsProvider();
+        FixedExtensibilityManager.FontsProvider = fontsProvider;
 ```
 
-3. Update the `FontsProvider` implementation to include the necessary fonts and their corresponding font files.

+            string fontFolder = Environment.GetFolderPath(Environment.SpecialFolder.Fonts);
+
+            //The fonts can differ depending on the file 
+            if (fontProperties.FontFamilyName == "Trebuchet MS")
+            {
+                if (fontProperties.FontStyle == FontStyles.Italic && fontProperties.FontWeight == FontWeights.Bold)
+                {
+                    fontFileName = $"trebucbi.ttf";
+                }
+                else if (fontProperties.FontStyle == FontStyles.Italic)
+                {
+                    fontFileName = $"trebucit.ttf";
+                }
+                else if (fontProperties.FontWeight == FontWeights.Normal)
+                {
+                    fontFileName = "trebuc.ttf";
+                }
+                else if (fontProperties.FontWeight == FontWeights.Bold)
+                {
+                    fontFileName = $"trebucbd.ttf";
+                }
+            }        
+            
+
+            //...add more fonts if needed... 
+
+            DirectoryInfo directory = new DirectoryInfo(fontFolder);
+            FileInfo[] fontFiles = directory.GetFiles();
 
-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.
+            var fontFile = fontFiles.FirstOrDefault(f => f.Name.Equals(fontFileName, StringComparison.InvariantCultureIgnoreCase));
+            if (fontFile != null)
+            {
+                var targetPath = fontFile.FullName;
+                using (FileStream fileStream = File.OpenRead(targetPath))
+                {
+                    using (MemoryStream memoryStream = new MemoryStream())
+                    {
+                        fileStream.CopyTo(memoryStream);
+                        return memoryStream.ToArray();
+                    }
+                }
+            }
+
+            return null;
+        }
+    }
+```
+Now, the font in the exported PDF document is the correct one and the text is not clipped.
 
-## 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.
