Formatting cells with the Google Sheets API

The Google Sheets API, introduced at Google I/O in 2016, offers new features such as cell formatting that were not available in previous versions, enhancing its functionality to align more closely with the Sheets user interfaces on desktop and mobile. The process of formatting cells, like bolding the first row of a sheet, is achieved by creating JSON payload requests and sending them to the API. This is demonstrated through a sample JavaScript code that sends a POST request to the Sheets API using the sheet ID and requests. The article highlights the importance of constructing JSON payloads correctly for API calls and provides resources like a deep-dive blog post and a JavaScript codelab to aid developers in managing data, such as customer orders, within Google Sheets. The video tutorial and accompanying resources aim to help developers leverage G Suite APIs for app enhancement, with future content set to explore integrating Google Sheets with Google Slides through API functionalities.
