Google Sheet Demo
This demo is using drive-db
to fetch a public Google Sheet and then xlsx
to save the data locally as test.xlsx
.
It uses modern Javascript; import/export
, async/away
, etc. To run this you need Node.js 12 or newer, and you will notice we added "type": "module"
to the package.json
.
Here is the full code:
import xlsx from "xlsx";
import drive from "drive-db";
(async () => {
const data = await drive("1fvz34wY6phWDJsuIneqvOoZRPfo6CfJyPg1BYgHt59k");
/* Create a new workbook */
const workbook = xlsx.utils.book_new();
/* make worksheet */
const worksheet = xlsx.utils.json_to_sheet(data);
/* Add the worksheet to the workbook */
xlsx.utils.book_append_sheet(workbook, worksheet);
xlsx.writeFile(workbook, "test.xlsx");
})();
Let's go over the different parts:
import xlsx from "xlsx";
import drive from "drive-db";
This imports both xlsx
and drive-db
libraries. While these are written in commonjs, Javascript Modules can usually import the commonjs modules with no problem.
(async () => {
// ...
})();
This is what is called an Immediately Invoked Function Expression. These are normally used to either create a new execution context, or in this case to allow to run async code easier.
const data = await drive("1fvz34wY6phWDJsuIneqvOoZRPfo6CfJyPg1BYgHt59k");
Using drive-db
, fetch the data for the given spreadsheet id. In this case it's this Google Sheet document, and since we don't specify the sheet it's the default one.
const workbook = xlsx.utils.book_new();
const worksheet = xlsx.utils.json_to_sheet(data);
We need to create a workbook with a worksheet inside. The worksheet is created from the previously fetched data. drive-db
exports the data in the same format that xlsx
's .json_to_sheet()
method expects, so it's a straightforward operation.
xlsx.utils.book_append_sheet(workbook, worksheet);
The worksheet needs to be inside the workbook, so we use the operation .book_append_sheet()
to make it so.
xlsx.writeFile(workbook, "test.xlsx");
Finally we save the workbook into a XLSX file in out filesystem. With this, now it can be opened by any spreadsheet program that we have installed.
