汇总来自多个文档的内容

编码级别：初级
时长：15 分钟
项目类型：通过自定义菜单实现自动化

目标

了解解决方案的用途。
了解 Apps 脚本服务在此解决方案中执行的操作。
设置脚本。
运行脚本。

关于此解决方案

为了节省时间并减少手动复制和粘贴错误，您可以将多个文档中的内容自动导入一个主文档中。此解决方案侧重于汇总项目状态报告，但您可以根据需要进行修改。

导入的项目摘要的屏幕截图

运作方式

该脚本会创建一个文件夹来存储要从中导入内容的文档和一个要开始导入的模板文档。该脚本还包含用于创建示例文档的函数，以演示此解决方案。

当用户从自定义菜单中选择导入摘要时，脚本会获取文件夹中的所有 Google 文档文件，并遍历每个文件。该脚本会查找特定的字符串和标题类型，以识别需要复制的摘要文本。复制文本后，脚本会更改标识符字符串的文本颜色以减少重复。脚本将摘要粘贴到主文档中，每个文档都位于各自的单个单元格表中。

Apps 脚本服务

此解决方案使用以下服务：

文档服务 - 创建模板和示例源文档。遍历每个源文档，查找要导入的新项目摘要。将摘要导入到主文档。更新源文档，以防止多次导入摘要。
云端硬盘服务 - 创建用于存储源文档的文件夹。将模板文档和示例源文档添加到该文件夹。
实用工具服务 - 设置脚本每次从源文档导入摘要时向主文档添加的日期。
基础服务 - 使用 Session 类获取脚本的时区。该脚本在将导入日期添加到主文档时会使用时区。

前提条件

如需使用此示例，您需要满足以下前提条件：

Google 帐号（Google Workspace 帐号可能需要管理员批准）。
能够访问互联网的网络浏览器。

设置脚本

点击下面的按钮以创建汇总内容文档的副本。
复制

运行脚本

运行包含示例文档的演示

依次点击导入摘要 > 配置 > 使用示例文档运行演示设置。您可能需要刷新页面才能看到此自定义菜单。
出现提示时，为脚本授权。如果 OAuth 同意屏幕显示 This app is not verify 警告，请依次选择 Advanced > Go to {Project Name} (unsafe)，以继续操作。
依次点击导入摘要 > 配置 > 使用示例文档运行演示设置。
出现提示时，复制云端硬盘文件夹的网址，以在后续步骤中使用。
点击 OK（确定）。
依次点击导入摘要 > 导入摘要。
出现提示时，点击 OK。
查看从示例文档导入的项目摘要。

添加和导入摘要

在新的浏览器标签页中，粘贴文件夹网址以打开项目状态文件夹。
打开 Project ABC 文件。
将以下内容添加到文档末尾，以创建新的要导入的摘要：
1. 输入 Summary 并将文本样式设置为标题 3。
2. 在 Summary 的正下方，插入一个 1x1 表格。请确保 Summary 和表之间没有空行。
3. 在表中，输入 Hello world!。
切换回主文档，然后依次点击导入摘要 > 导入摘要。
出现提示时，点击 OK。
在文档末尾查看最新导入的内容。
