Step by Step Guide to Building a Microsoft Word API Integration in Go

Aug 7, 20245 minute read

Introduction

Hey there, fellow Go enthusiasts! Ready to dive into the world of document manipulation? Today, we're going to build a Microsoft Word API integration using Go and the awesome unioffice package. Buckle up, because we're about to make document creation a breeze!

Prerequisites

Before we jump in, make sure you've got:

  • Go installed on your machine (if not, head over to golang.org and sort that out)
  • The unioffice package (grab it with go get github.com/unidoc/unioffice)

Setting up the project

Let's kick things off by creating a new Go module:

mkdir word-api-integration cd word-api-integration go mod init word-api-integration

Now, let's import the packages we'll need:

package main import ( "github.com/unidoc/unioffice/document" "github.com/unidoc/unioffice/measurement" "github.com/unidoc/unioffice/schema/soo/wml" ) func main() { // We'll add our magic here soon! }

Creating a new Word document

Time to create our first document:

doc := document.New() para := doc.AddParagraph() run := para.AddRun() run.AddText("Hello, Word!")

Just like that, we've got a document with some text. Easy peasy!

Working with document structure

Let's add some structure to our document:

// Add a new section section := doc.AddSection() // Set up header header := section.AddHeader() para := header.AddParagraph() para.AddRun().AddText("This is a header") // Set up footer footer := section.AddFooter() para = footer.AddParagraph() para.AddRun().AddText("This is a footer")

Formatting text

Want to make your text pop? Let's add some style:

para := doc.AddParagraph() run := para.AddRun() run.Properties().SetBold(true) run.Properties().SetSize(20) run.Properties().SetFont("Arial") run.AddText("This text is bold, size 20, and in Arial!")

Inserting and manipulating tables

Tables are a great way to organize information:

table := doc.AddTable() row := table.AddRow() cell := row.AddCell() cell.AddParagraph().AddRun().AddText("I'm in a table cell!")

Adding images

Let's spice things up with an image:

img, err := doc.AddImage("path/to/your/image.jpg") if err != nil { log.Fatal(err) } para := doc.AddParagraph() run := para.AddRun() drawing, _ := run.AddDrawing() drawing.SetSize(2*measurement.Inch, 2*measurement.Inch) drawing.SetImage(img)

Creating and updating fields

Dynamic content? No problem:

para := doc.AddParagraph() run := para.AddRun() field := run.AddField(document.FieldCurrentTime) field.SetUpdateOnOpen(true)

Saving and exporting the document

Let's wrap it up and save our masterpiece:

err := doc.SaveToFile("awesome_document.docx") if err != nil { log.Fatal(err) }

Error handling and best practices

Remember, always check for errors and handle them gracefully. Also, when working with large documents, consider using buffered writes to improve performance.

Conclusion

And there you have it! You've just created a Word document programmatically using Go. Pretty cool, right? This is just scratching the surface of what's possible with unioffice. Feel free to explore more advanced features and really make your documents shine!
