Create Or Replace Excel Sheet From Azure Net Job

On this article, I wish to share the steps and code to create/replace an Excel sheet from an Azure internet job. Utilizing Microsoft.Interop.Excel, we are able to create and replace the Excel sheet however in Azure internet jobs, we couldn’t use that DLL file, as an alternative of Microsoft. Interop dll, we are able to use the OpenXML spreadsheet choice to create or replace the Excel from the Azure internet job.

Let’s see the right way to create an Azure internet job together with the deployment steps and approaches to create or replace Excel.

What are the accessible choices to create or replace Excel?

  • Utilizing the Microsoft.Interop.Excel
  • OLEDB Connection
  • OpenXML Spreadsheet
  • Microsoft Excel 15.0 Object Library
  • Third-party DLLs

Right here, I wish to share the code for the OpenXML spreadsheet, since Microsoft.Interop.Excel and OLEDB can’t work on Azure internet jobs.

What’s an Azure Net Job?

Net Jobs is a function of Azure App Service that allows you to run a program or script in the identical context as an internet app, API app, or cell app. There is no such thing as a extra value to make use of Net Jobs.

Steps to Create Azure Net Job

Step 1. Open Visual Studio in your machine (I’m utilizing 2015 VS).

Step 2. Then, choose the “Azure Net Job” from Visual Studio.

Step 3. Present the title for the online job, choose the placement, and click on “OK” to create a brand new answer.

Select the location

Your undertaking shall be created efficiently.


Step 4. After the undertaking is created, simply construct the answer to revive the NuGet packages.

Step 5. Then, write the code inside the primary operate. Within the pattern, I’ve retrieved the information from the SQL DB desk utilizing View and now I’m updating within the Excel sheet.

Required DLL’s

utilizing System.Runtime.InteropServices;
utilizing DocumentFormat.OpenXml.Packaging;
utilizing DocumentFormat.OpenXml.Spreadsheet;
utilizing System.Collections.Generic;
utilizing DocumentFormat.OpenXml;



Right here is the pattern code for the ExportDataSetToExcel technique.

  • Cross your dataset on the tactic
  • Sheet Identify
  • SPath for the Excel sheet and
// Write the view knowledge to the excel
personal static void ExportDataSetToExcel(DataSet ds, string SheetName, string reportPath)
    string consequence = string.Empty;
        string filePath = reportPath;
        if (File.Exists(filePath))
        if (ds.Tables.Rely > 0 && ds.Tables[0] != null && ds.Tables[0].Columns.Rely > 0)
            System.Information.DataTable desk = ds.Tables[0];
            utilizing (var spreadsheetDocument = SpreadsheetDocument.Create(filePath, SpreadsheetDocumentType.Workbook))
                // Create SpreadsheetDocument
                WorkbookPart workbookPart = spreadsheetDocument.AddWorkbookPart();
                workbookPart.Workbook = new Workbook();
                var sheetPart = spreadsheetDocument.WorkbookPart.AddNewPart<WorksheetPart>();
                var sheetData = new SheetData();
                sheetPart.Worksheet = new Worksheet(sheetData);
                Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
                string relationshipId = spreadsheetDocument.WorkbookPart.GetIdOfPart(sheetPart);
                Sheet sheet = new Sheet()
                    Id = relationshipId,
                    SheetId = 1,
                    Identify = desk.TableName
                // Add header to sheetData
                Row headerRow = new Row();
                Checklist<string> columns = new Checklist<string>();
                foreach (DataColumn column in desk.Columns)
                    Cell cell = new Cell();
                    cell.DataType = CellValues.String;
                    cell.CellValue = new CellValue(column.ColumnName);
                // Add cells to sheetData
                foreach (DataRow row in desk.Rows)
                    Row newRow = new Row();
                    columns.ForEach(col =>
                        Cell cell = new Cell();
                        // If worth is DBNull, don't set worth to cell
                        if (row[col] != System.DBNull.Worth)
                            cell.DataType = CellValues.String;
                            cell.CellValue = new CellValue(row[col].ToString());
                Console.WriteLine($"Export {desk.Rows.Rely} rows of information to excel efficiently.");
        // string storageConnectionString = ConfigurationManager.ConnectionStrings["AzureWebJobsStorage"].ConnectionString.ToString();
        // var storageAccount = CloudStorageAccount.Parse(storageConnectionString);
        // CloudBlobClient cloudBlobClient = storageAccount.CreateCloudBlobClient();
        // var container = cloudBlobClient.GetContainerReference("emsreportcontainer");
        // Write the excel to Azure storage container
        // utilizing (FileStream fileStream = File.Open(filePath, FileMode.Open))
        // {
        //     bool exists = container.CreateIfNotExists();
        //     var blob = container.GetBlockBlobReference(SheetName + ".xslx");
        //     blob.DeleteIfExists();
        //     blob.UploadFromStream(fileStream);
        // }
    catch (Exception ex)
        Console.WriteLine($"Export motion failed. Error Message: {ex.Message}");
    // return consequence;
