How to create a blank Excel XLSX spreadsheet in C# .NET Framework

Want to implement Excel file creation in a hurry? We’ve got you covered. You’ll be done in a matter of minutes!

Let us get started by using NuGet to install our API client. To do this, simply run this command in your Package Manager console.

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 2.2.0

Now just run EditDocumentXlsxCreateBlankSpreadsheet with the following code excerpt.

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class EditDocumentXlsxCreateBlankSpreadsheetExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new EditDocumentApi();
var input = new CreateBlankSpreadsheetRequest(); // CreateBlankSpreadsheetRequest | Document input request
try
{
// Create a blank Excel XLSX spreadsheet
CreateBlankSpreadsheetResponse result = apiInstance.EditDocumentXlsxCreateBlankSpreadsheet(input);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling EditDocumentApi.EditDocumentXlsxCreateBlankSpreadsheet: " + e.Message );
}
}
}
}

And that’s a wrap. Our blank XLSX file is ready and waiting to be populated. Our other functions cover XLSX editing as well, allowing you to add and delete cell information as needed.
