Sorting data in Excel is a fundamental skill that enhances data organization and analysis. By rearranging rows based on specific criteria—such as alphabetical order, numerical value, or date—users can easily identify trends, patterns, and outliers. In this article, you will learn how to sort data in Excel using C# with Spire.XLS for .NET.
Install Spire.XLS for .NET
To begin with, you need to add the DLL files included in the Spire.XLS for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

Sort a Single Column in Excel in C#
Sorting a single column in Excel enables quick organization of your data in ascending or descending order for easier analysis. However, this method leaves other columns unchanged, potentially leading to misalignment of related data.
Spire.XLS for .NET provides the Workbook.DataSorter.SortColumns.Add(int key, SortComparisonType sortComparisonType, OrderBy orderBy) method. This method enables developers to set sorting criteria by selecting a specific column, defining the comparison type, and specifying the sort order (ascending or descending). To apply the sorting to the defined range, use the Workbook.DataSorter.Sort(CellRange range) method.
Here are the steps to sort a single column in Excel using C#:
- Create a Workbook object.
- Load an Excel file using the Workbook.LoadFromFile() method.
- Get a specific worksheet using the Workbook.Worksheets[index] property.
- Get the column where you want to sort data using the Worksheet.Range property.
- Create sorting criteria for the selected column using the Workbook.DataSorter.SortColumns.Add() method.
- Execute sorting within the column using the Workbook.DataSorter.Sort() method.
- Save the workbook to a different Excel file.
- C#
using Spire.Xls;
namespace SortSingleColumn
{
class Program
{
static void Main(string[] args)
{
// Create a Workbook object
Workbook workbook = new Workbook();
// Load an Excel file
workbook.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.xlsx");
// Get a specific worksheet
Worksheet sheet = workbook.Worksheets[0];
// Get the cell range (a single column) where you want to sort data
CellRange cellRange = sheet.Range["F1:F6"];
// Sort values in the specified column in descending order
workbook.DataSorter.SortColumns.Add(5, SortComparsionType.Values, OrderBy.Descending);
// Sort in the specified cell range
workbook.DataSorter.Sort(cellRange);
// Save the workbook
workbook.SaveToFile("SortSingleColumn.xlsx", ExcelVersion.Version2013);
// Dispose resources
workbook.Dispose();
}
}
}
Sort Multiple Columns in Excel in C#
Sorting data across multiple columns ensures that all related data across the selected columns remains aligned and meaningful, which is useful for complex datasets where relationships between data points matter.
Sorting data across multiple columns is similar to sorting a single column. The main difference lies in the CellRange parameter used in Workbook.DataSorter.Sort(CellRange range), which specifies multiple columns instead of just one.
Here are the steps to sort multiple column in Excel using C#:
- Create a Workbook object.
- Load an Excel file using the Workbook.LoadFromFile() method.
- Get a specific worksheet using the Workbook.Worksheets[index] property.
- Get the cell range (columns) where you want to sort data using the Worksheet.Range property.
- Create sorting criteria for the selected column using the Workbook.DataSorter.SortColumns.Add() method.
- Execute sorting within the range using the Workbook.DataSorter.Sort() method.
- Save the workbook to a different Excel file.
- C#
using Spire.Xls;
namespace SortMultipleColumns
{
class Program
{
static void Main(string[] args)
{
// Create a new workbook
Workbook workbook = new Workbook();
// Load an Excel file
workbook.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.xlsx");
// Get a specific worksheet
Worksheet sheet = workbook.Worksheets[0];
// Get the cell range (multiple columns) where you want to sort data
CellRange cellRange = sheet.Range["A1:F6"];
// Sort values in the specified column in descending order
workbook.DataSorter.SortColumns.Add(5, SortComparsionType.Values, OrderBy.Descending);
// Sort in the specified cell range
workbook.DataSorter.Sort(cellRange);
// Save the workbook
workbook.SaveToFile("SortMultipleColumns.xlsx", ExcelVersion.Version2013);
// Dispose resources
workbook.Dispose();
}
}
}
Sort by a Custom List in C#
Sorting by a custom list in Excel allows you to arrange data based on specific, non-alphabetical criteria tailored to your needs, ensuring the order is meaningful for your analysis or reporting.
To accomplish this, create an array of strings that defines the custom sorting order. Next, set the sorting criteria using the Workbook.DataSorter.SortColumns.Add(int key, OrderBy orderBy) method. Finally, invoke the Workbook.DataSorter.Sort(CellRange range) method to sort the specified cell range.
Here are the steps to sort data by a custom list in Excel using C#:
- Create a Workbook object.
- Load an Excel file using the Workbook.LoadFromFile() method.
- Get a specific worksheet using the Workbook.Worksheets[index] property.
- Get the cell range where you want to sort data using the Worksheet.Range property.
- Define the custom sorting order with an array of strings.
- Create sorting criteria for the selected column using the Workbook.DataSorter.SortColumns.Add() method.
- Execute sorting within the range using the Workbook.DataSorter.Sort() method.
- Save the workbook to a different Excel file.
- C#
using Spire.Xls;
namespace SortMultipleColumns
{
class Program
{
static void Main(string[] args)
{
// Create a new workbook
Workbook workbook = new Workbook();
// Load an Excel file
workbook.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.xlsx");
// Get a specific worksheet
Worksheet sheet = workbook.Worksheets[0];
// Get the cell range where you want to sort data
CellRange cellRange = sheet.Range["A1:F6"];
String[] customList = { "Central", "North", "South", "East", "West" };
// Sort a specified column using the custom list
workbook.DataSorter.SortColumns.Add(0, customList);
// Sort in the specified cell range
workbook.DataSorter.Sort(cellRange);
// Save the workbook
workbook.SaveToFile("SortByCustomList.xlsx", ExcelVersion.Version2013);
// Dispose resources
workbook.Dispose();
}
}

Converting Word to TIFF can be useful in various scenarios. TIFF files have high quality and wide support, making them versatile for sharing documents. The conversion also "flattens" the Word document, preserving the layout so it appears exactly as the original. This can be helpful when the document needs to be incorporated into another application or workflow that requires image-based files.
In this article, you will learn how to convert Word to TIFF using C# and the Spire.Doc for .NET library.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Convert Word to TIFF in C#
Spire.Doc for .NET provides the Document.SaveToImages() method, which enables developers to convert an entire document into an array of images. Subsequently, these individual images can be combined into a single TIFF image using the built-in .NET library.
The steps to convert Word to TIFF using C# are as follows.
- Create a Document object.
- Load a Word document using Document.LoadFile() method.
- Convert the document into an array of images using Document.SaveToImages() method.
- Combine these images into a single TIFF file using the custom method ConvertImagesToTiff().
- C#
using Spire.Doc;
using Spire.Doc.Documents;
using System.Drawing;
using System.Drawing.Imaging;
namespace WordToTiff
{
class Program
{
static void Main(string[] args)
{
// Create a Document object
Document doc = new Document();
// Load a Word document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");
// Convert the whole document to images
Image[] images = doc.SaveToImages(ImageType.Bitmap);
// Convert multiple images into a TIFF file
ConvertImagesToTiff(images, "ToTiff.tiff", EncoderValue.CompressionLZW);
// Dispose resource
doc.Dispose();
}
private static ImageCodecInfo GetEncoderInfo(string mimeType)
{
// Get the image encoders
ImageCodecInfo[] encoders = ImageCodecInfo.GetImageEncoders();
for (int j = 0; j < encoders.Length; j++)
{
// Find the encoder that matches the specified MIME type
if (encoders[j].MimeType == mimeType)
return encoders[j];
}
throw new Exception(mimeType + " mime type not found in ImageCodecInfo");
}
public static void ConvertImagesToTiff(Image[] images, string outFile, EncoderValue compressEncoder)
{
// Set the encoder parameters
Encoder enc = Encoder.SaveFlag;
EncoderParameters ep = new EncoderParameters(2);
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame);
ep.Param[1] = new EncoderParameter(Encoder.Compression, (long)compressEncoder);
// Get the first image
Image pages = images[0];
// Create a variable
int frame = 0;
// Get an ImageCodecInfo object for processing TIFF image codec information
ImageCodecInfo info = GetEncoderInfo("image/tiff");
// Iterate through each Image
foreach (Image img in images)
{
// If it's the first frame, save it to the output file with specified encoder parameters
if (frame == 0)
{
pages = img;
pages.Save(outFile, info, ep);
}
else
{
// Save the intermediate frames
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
pages.SaveAdd(img, ep);
}
// If it's the last frame, flush the encoder parameters and close the file
if (frame == images.Length - 1)
{
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush);
pages.SaveAdd(ep);
}
frame++;
}
}
