Sort and Filter

This guide will show how to add a sorting and filtering to spreadsheet using UniOffice.

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/sort-filter folder in the unioffice-examples directory.

cd unioffice-examples/spreadsheet/sort-filter/

How it works

The import section in lines 4-11 imports the necessary packages from UniOffice and the Go standard library.
Then init function following the import section is used to initialize the package by setting the metered license key from the system’s environment using license.SetMeteredKey(os.Getenv(`UNIDOC_LICENSE_API_KEY`)).

The main function defined in lines 22-50 contains the code that creates a workbook with a sorting filter added. First it creates a new workbook with an empty sheet in lines 23-26. Then the header row is created following that. This done the following snippet.

hdrRow := sheet.AddRow()
hdrRow.AddCell().SetString("Product Name")

The for loop in lines 34-40 adds the rest of the rows populated with data. Then the rows are sorted based on column C using:

sheet.Sort("C", 2, spreadsheet.SortOrderDescending)

The arguments passed to the Sort method are the column name, the first row and the ordering type in order. Finally, the workbook is validated and saved to file in lines 45-49.

Run the code

Use the following command to run the code.

go run main.go
