Convert to PDF

The process of converting a spreadsheet file to PDF using UniOffice library will be demonstrated in this guide.

Before you begin

You should get your API key from your UniCloud account.

If this is your first time using UniOffice SDK, follow this guide to set up a local development environment.

Clone the project repository

In your terminal, clone the examples repository. It contains the Go code we will be using for this guide.

git clone

To get the example navigate to the path spreadsheet/convert_to_pdf folder in the unioffice-examples directory.

cd unioffice-examples/spreadsheet/convert_to_pdf/

How it works

The import section and the init function are defined in lines 6-15 and 17-28 accordingly. The main function is defined in lines 33-54. The for loop iterates through each file name and converts the spreadsheet to PDF. First a workbook is object is created from a given file using spreadsheet.Open(filename + ".xlsx"). Then the for loop iterates through each sheet of the workbook file and converts it to PDF using:

c := convert.ConvertToPdf(&s)
err = c.WriteToFile(fmt.Sprintf("%s/sheet_%d.pdf", filename, si))
if err != nil {
  log.Fatalf("error saving PDF: %s", err)
