- multiple auth options - service account (w/ optional impersonation), OAuth 2.0, API key (read-only)
- cell-based API - read, write, bulk-updates, formatting
- row-based API - read, update, delete (based on the old v3 row-based calls)
- managing worksheets - add, remove, resize, change title, formatting

> **🚨 Google Deprecation Warning - affects older version (v2) of this module 🚨**
>
> Google is [phasing out their old v3 api](https://cloud.google.com/blog/products/g-suite/migrate-your-apps-use-latest-sheets-api), which the older version of this module used. Originally they were going to shut it down on March 3rd 2020, but have pushed that date back to June 2021.


**Regardless, please upgrade to the latest version of this module (v3) which uses the newer sheets v4 API**

-------------

> 🌈 **Installation** - `npm i google-spreadsheet --save` or `yarn add google-spreadsheet`

## Examples
_the following examples are meant to give you an idea of just some of the things you can do_

> **IMPORTANT NOTE** - To keep the examples concise, I'm calling await [at the top level](https://v8.dev/features/top-level-await) which is not allowed by default in most versions of node. If you need to call await in a script at the root level, you must instead wrap it in an async function like so:

```javascript
(async function() {
  await someAsyncFunction();
}());
```


### The Basics
```javascript
const { GoogleSpreadsheet } = require('google-spreadsheet');

// Initialize the sheet - doc ID is the long id in the sheets URL
const doc = new GoogleSpreadsheet('<the sheet ID from the url>');

// Initialize Auth - see https://theoephraim.github.io/node-google-spreadsheet/#/getting-started/authentication
await doc.useServiceAccountAuth({
  // env var values are copied from service account credentials generated by google
  // see "Authentication" section in docs for more info
  client_email: process.env.GOOGLE_SERVICE_ACCOUNT_EMAIL,
  private_key: process.env.GOOGLE_PRIVATE_KEY,
});

await doc.loadInfo(); // loads document properties and worksheets
console.log(doc.title);
await doc.updateProperties({ title: 'renamed doc' });

const sheet = doc.sheetsByIndex[0]; // or use doc.sheetsById[id] or doc.sheetsByTitle[title]
console.log(sheet.title);
console.log(sheet.rowCount);

// adding / removing sheets
const newSheet = await doc.addSheet({ title: 'hot new sheet!' });
await newSheet.delete();
```

### Working with rows
```javascript
// create a sheet and set the header row
const sheet = await doc.addSheet({ headerValues: ['name', 'email'] });

// append rows
const larryRow = await sheet.addRow({ name: 'Larry Page', email: 'larry@google.com' });
const moreRows = await sheet.addRows([
  { name: 'Sergey Brin', email: 'sergey@google.com' },
  { name: 'Eric Schmidt', email: 'eric@google.com' },
]);

// read rows
const rows = await sheet.getRows(); // can pass in { limit, offset }

// read/write row values
console.log(rows[0].name); // 'Larry Page'
rows[1].email = 'sergey@abc.xyz'; // update a value
await rows[1].save(); // save updates
await rows[1].delete(); // delete a row
```

### Working with cells
```javascript
await sheet.loadCells('A1:E10'); // loads range of cells into local cache - DOES NOT RETURN THE CELLS
console.log(sheet.cellStats); // total cells, loaded, how many non-empty
const a1 = sheet.getCell(0, 0); // access cells using a zero-based index
const c6 = sheet.getCellByA1('C6'); // or A1 style notation
// access everything about the cell
console.log(a1.value);
console.log(a1.formula);
console.log(a1.formattedValue);
// update the cell contents and formatting
a1.value = 123.456;
c6.formula = '=A1';
a1.textFormat = { bold: true };
c6.note = 'This is a note!';
await sheet.saveUpdatedCells(); // save all updates in one call
```

## Why?
> **This module provides an intuitive wrapper around Google's API to simplify common interactions**

While Google's v4 sheets api is much easier to use than v3 was, the official [googleapis npm module](https://www.npmjs.com/package/googleapis) is a giant meta-tool that handles _every Google product_. The module and the API itself are awkward and the docs are pretty terrible, at least to get started.

**In what situation should you use Google's API directly?**<br>
This module makes trade-offs for simplicity of the interface.
Google's API provides a mechanism to make many requests in parallel, so if speed and efficiency is extremely important to your use case, you may want to use their API directly. There are also several features of their API that are not implemented here yet.
