GIRITON attendance also offers a REST api for all work with data which companies can use to integrate GIRITON into other internal company systems.
Google Sheets can use the REST api and it is so easy to connect data from GIRITON to your Google Sheet. For example, every time you open a Google Sheet, you can retrieve a list of currently present persons from GIRITON, write them on a sheet of your spreadsheet, and use your own Excel formulas to further work with this data. More info can be found in the online help here.
