I want to use UiPath with C# Invoke Code to open a Word document and insert the text “Hello World” with center alignment. How can I do this?

This quote literally entered as a prompt in ChatGPT:

ChatGPT - UiPath C# Word Automation

I didn’t validate the code (simply too lazy) but it should give you a decent code snip to work with.

Here the error, when i try to run the workflow…

Hi @Vhierdy_Hafidz

Use the below C# code in Invoke Code:

// Create a new instance of Word application
var wordApp = new Microsoft.Office.Interop.Word.Application();
wordApp.Visible = true; // Set Word visible

// Create a new document
var document = wordApp.Documents.Add();

// Add a new paragraph and insert "Hello World"
var paragraph = document.Content.Paragraphs.Add();
paragraph.Range.Text = "Hello World";

// Align the text to the center
paragraph.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;

// Save the document to a specific path
string savePath = @"C:\Users\" + Environment.UserName + @"\Documents\UiPath\Dummy\Document.docx"; // Use @ to create a verbatim string
document.SaveAs2(savePath);

// Optionally, you can close the document after saving
document.Close();
wordApp.Quit();

Note: Please change the path savePath according to yours.

Output:

Hope it helps!!

You may need to remove those Using statements and import the namespaces in the project itself if not yet done.

Also check if your project is set to VB or C# looking at the ‘line 5 error’.
The similair solution also works in VB, you just need to use VB syntax. The used interop methods remain the same.
