<<Purpose and Content Introduction>>

This book is an introductory guide to automating daily tasks by linking Google Apps Script and Slack. While it does not cover the basic JavaScript syntax of Google Apps Script, it proceeds with a step-by-step explanation through concrete code examples across 13 chapters, so we recommend those new to Google Apps Script to read from Chapter 1. Chapters 3 and 4 provide a detailed explanation of the mechanism of Incoming Webhooks, which send messages from programs to Slack, and explain specific message sending methods in conjunction with Google Apps Script with code examples. Furthermore, Chapters 5 and 6 cover how to operate Google Forms and Google Sheets from Google Apps Script, and Chapter 7 deepens understanding through advanced practice problems combining these. Chapter 8 explains the mechanism of slash commands that call programs from Slack, including the differences from Incoming Webhooks, and also provides sample scripts for automation in limited use cases that cannot be handled by Workflow Builder. Through these explanations, you will be able to acquire concrete ideas for improving daily tasks and practical automation methods.

(Impress NextPublishing inherits the digital-first publishing model developed by Impress R&D, realizing a wide range of publishing plans quickly and sustainably through e-books + on-demand printing.)
