gsheetdb

Use Google Sheets as a database.

---

Preparing the spreadsheet

1. Activate Google Sheets API. Go to the Google API Console Library and enable Google Sheets API.

2. Create a Project. Go to the Dashboard and click on Credentials in the sidebar. If this is the first time you set this up, you will need to create a new project. Otherwise you can either use an existing project or create a new one from the project drop down menu in the navigation bar.

3. Create a Service Account. Once you've got a project, from the Credentials section, click on Create Credentials from the top and select Service account from the drop down menu. Provide a name and an ID (which will become an e-mail address). Then you'll be asked for a role. You need Read & Write permissions so Project > Owner would work well. Fill in the optional fields if you wish.

4. Create the JSON key. You'll be redirected to the Credentials page. Scroll down to the bottom of the page and edit your service account by clicking on the pen icon. In the Keys section, Add Key and make sure you choose JSON. You'll be downloading a JSON file; save it preciously. While you're here in the KAlso make a note of your service account e-mail address.

5. Set up your spreadsheet. Create or open the Google Sheet you wish to use as your database. Click on Share and under People, paste the e-mail address from your service account (you can find it again on the Google Console, in the Credentials section of your project, under Service Accounts at the end of the page). Share.

That's it! In the JS code below, you'll see that you will need to provide the JSON key you just downloaded. DO NOT commit the JSON key! Add the file to .gitignore now and import it into the code! Or use environment variables.

Let's assume this spreadsheet:

.	A	B	C
1	date	amount	description
2	today	123	abc

The first row will always be considered as headers.

Connecting to the sheet

import gsheetdb from 'gsheetdb'

let db = new gsheetdb({
  spreadsheetId: 'sheetId', // replace with spreadsheet id (from URL)
  sheetName: 'sheetName',   // replace with sheet name
  credentialsJSON: {}       // replace with JSON formatted credentials
})

Getting the data

So let's begin to read some data:

let data = await db.getData()

Data returned will look like:

[
  {
    values: [ 'today', 123, 'abc' ],
    rowNb: 2
  }
]

Would you prefer to get the data in key: value format?

[
  {
    date: 'today',
    amount: 123,
    description: 'abc',
    rowNb: 2
  }
]

Insert rows

To add rows to the spreadsheet:

await db.insertRows([
  ['tomorrow', 456, 'def'],
  ['monday', 23, 'ghi']
])

And the spreadsheet will look like this:

.	A	B	C
1	date	amount	description
2	today	123	abc
3	tomorrow	456	def
4	monday	23	ghi

Update a row

To update a row, provide the spreadsheet row number (not the array id):

await db.updateRow(
  3, ['yesterday', 456, 'def']
)

.	A	B	C
1	date	amount	description
2	today	123	abc
3	yesterday	456	def
4	monday	23	ghi

Would it be useful to be able to update several rows at a time?
