What is Google Sheets API?

The Google Sheets API lets you read and modify any aspect of a spreadsheet. Spreadsheets have many settings that let you craft beautiful and functional sheets, so the API has many settings too.

Spreadsheets can have multiple sheets, with each sheet having any number of rows or columns. A cell is a location at the intersection of a particular row and column, and may contain a data value. The Google Sheets API provides the spreadsheets.values collection to enable the simple reading and writing of values.

To read data from a sheet, you will need the spreadsheet ID and the range(s) A1 notation.

To write to a sheet, you will need the spreadsheet ID, the range(s) in A1 notation, and the data you wish to write arranged in an appropriate request body object.
