+title: Excel file with uninstalled fonts converted to PDF/Image | Syncfusion
+description: This page tells what happens when an Excel file containing uninstalled fonts is converted to PDF/Image using XlsIO.
+platform: File-formats
+control: XlsIO
+documentation: UG
+---
+
+# How does Excel file with uninstalled fonts is converted to PDF/Image?
+
+When the fonts used in particular Excel document are not installed in the machine, the desired characters will be missing in the PDF/Image conversion. However, XlsIO comes up with a font substitution method through **SubstituteFontEventHandler** event. This will enable user to specify alternate font name to render the characters in the specified alternate font. Otherwise, Microsoft Sans Serif is used as the default one.
+
+N> Due to this font substitution, there might be a slight difference with the rendered text in the generated PDF/Image files during Excel to PDF/Image conversion.

+# How to avoid exception when adding worksheets with same name?
+
+Microsoft Excel throws exception when adding worksheet with existing worksheet name in a workbook and XlsIO does the same. But in some case, if you want to add worksheets with the same name using XlsIO then you can avoid the exception in XlsIO by setting IApplication IgnoreSheetNameException property as true.

+
+StackOverflow exception occurs when the number of <i>IterationMaxCount</i>, <i>MaximumRecursiveCalls</i> and <i>MaxStackDepth</i> exceeds in the `CalcEngine`. To avoid this StackOverflow exception while computing the formulas iteratively exceeding the maximum capacity, you need to set the values for these properties before calling the <b>Calculate</b> method of <b>IWorksheet</b> interface.

+
+The [UnauthorizedAccessException](https://docs.microsoft.com/en-us/dotnet/api/system.unauthorizedaccessexception?view=netcore-3.1) occurs when you are trying to write in a read-only/hidden file or if you don’t have access to the particular folder that contains the file or the folder might be locked currently. 
+
+First, check whether you can access the folder and the file directly. Then, right-click the input file and check whether the Read-only/Hidden checkbox is checked. If it is checked, kindly uncheck the Read-only/Hidden checkbox and try running the project as an administrator or an authorized user to access the file folder.

+# How to protect certain cells in a worksheet?
+
+All the cells in an Excel worksheet have a Locked property, which determines if the cell will be editable. When a worksheet is protected, all the cells in the worksheet get locked, by default.

+# How to protect the zip files using Syncfusion.Compression.Base?
+
+Password is used for protecting files which needs more security. This can be achieved by using various encryption algorithms. The compressed zip files can be protected using encryption algorithms with password as a key for that algorithm. 
+
+Syncfusion.Compression.Base supports AES-128 bits, AES-192 bits, AES-256 bits and ZipCrypto encryption algorithms. These encryption algorithms are available under the enumeration **EncryptionAlgorithm**.
+
+The following complete code snippet explains how to protect a zip file with password using AES-256 bits encryption algorithm.

+
+# In which situation we use AutoDetectComplexScript converter property?
+
+Complex script languages are some languages (eg., Arabic) which stores text differently from how it is displayed. Many such languages use bidirectional script which means, words and sentences are written from right to left, while some text such as numbers and Roman-based words are written from left to right. 
+
+If your input Excel file contains such complex script languages, then the AutoDetectComplexScript property can be used to render them in PDF.

+
+# What is the image quality when using the ExportQualityImage property?
+
+Normally, the image in the PDF will be saved in PNG format. With this property, the TIFF format is used for exporting the images into PDF. 
+
+**TIFF (non-default):**
+TIFF uses a lossless compression algorithm in order to preserve as much quality in the image. They are high resolution files with larger sizes. They are no longer supported on many websites, due to their slower loading time. If you can still open the file, it will take much longer to download or load in the browser due to their size. Since they preserve the most quality, they are best used for printing to paper and even billboard signs.
+
+**PNG (default):**
+PNG is ideal even for complex images. If you require more detail in graphics, then PNG is better. PNG provides the best support for transparency. PNG is ideal for static images, logos, prints and other images with transparent background.
+
+Hence, we have used PNG format as default for exporting the images into PDF. If you are concerned only about the image quality and not about file size and loading time, then you can use the non-default with the **ExportQualityImage** property.
