Edit Google Spreadsheet

> A simple API for reading and writing Google Spreadsheets in Node.js

This module aims to be a complete wrapper around the Google Sheets API version 3.0. If anything is missing, create an issue, or even better, a pull request.



:warning: Google has finally deprecated ClientLogin, which means you can no longer authenticate with your email and password. See https://github.com/jpillora/node-edit-google-spreadsheet/issues/72 for updates.

#### Install
``
npm install edit-google-spreadsheet
`

#### Basic Usage

Load a spreadsheet:

` js
var Spreadsheet = require('edit-google-spreadsheet');

Spreadsheet.load({
debug: true,
spreadsheetName: 'edit-spreadsheet-example',
worksheetName: 'Sheet1',

// Choose from 1 of the 5 authentication methods:

// 1. Username and Password has been deprecated. OAuth2 is recommended.

// OR 2. OAuth
oauth : {
email: 'my-name@google.email.com',
keyFile: 'my-private-key.pem'
},

// OR 3. OAuth2 (See get_oauth2_permissions.js)
oauth2: {
client_id: 'generated-id.apps.googleusercontent.com',
client_secret: 'generated-secret',
refresh_token: 'token generated with get_oauth2_permission.js'
},

// OR 4. Static Token
accessToken: {
type: 'Bearer',
token: 'my-generated-token'
},

// OR 5. Dynamic Token
accessToken: function(callback) {
//... async stuff ...
callback(null, token);
}
}, function sheetReady(err, spreadsheet) {
//use speadsheet!
});
`

Note: Using the options spreadsheetName and worksheetName will cause lookups for spreadsheetId and worksheetId. Use spreadsheetId and worksheetId for improved performance.

Update sheet:

` js
function sheetReady(err, spreadsheet) {
if(err) throw err;

spreadsheet.add({ 3: { 5: "hello!" } });

spreadsheet.send(function(err) {
if(err) throw err;
console.log("Updated Cell at row 3, column 5 to 'hello!'");
});
}
`

Read sheet:

` js
function sheetReady(err, spreadsheet) {
if(err) throw err;

spreadsheet.receive(function(err, rows, info) {
if(err) throw err;
console.log("Found rows:", rows);
// Found rows: { '3': { '5': 'hello!' } }
});

}
`

#### async / await Usage

All functions which have a callback return a Promise tied
to that callback and can therefore be used with async / await.

`js

const Spreadsheet = require("../");

(async function example() {
let spreadsheet = await Spreadsheet.load({
debug: true,
oauth2: ...,
spreadsheetName: "node-spreadsheet-example",
worksheetName: "Sheet1"
});
//receive all cells
let [rows, info] = await spreadsheet.receive({getValues: false});
console.log("Found rows:", rows);
console.log("With info:", info);
})().catch;
`

#### Metadata

Get metadata

` js
function sheetReady(err, spreadsheet) {
if(err) throw err;

spreadsheet.metadata(function(err, metadata){
if(err) throw err;
console.log(metadata);
// { title: 'Sheet3', rowCount: '100', colCount: '20', updated: [Date] }
});
}
`

Set metadata

` js
function sheetReady(err, spreadsheet) {
if(err) throw err;

spreadsheet.metadata({
title: 'Sheet2'
rowCount: 100,
colCount: 20
}, function(err, metadata){
if(err) throw err;
console.log(metadata);
});
}
`

WARNING: all cells outside the range of the new size will be silently deleted

#### More add Examples

Batch edit:

` js
spreadsheet.add([[1,2,3],
[4,5,6]]);
`

Batch edit starting from row 5:

` js
spreadsheet.add({
5: [[1,2,3],
[4,5,6]]
});
`

Batch edit starting from row 5, column 7:

` js
spreadsheet.add({
5: {
7: [[1,2,3],
[4,5,6]]
}
});
`

Formula building with named cell references:
` js
spreadsheet.add({
3: {
4: { name: "a", val: 42 }, //'42' though tagged as "a"
5: { name: "b", val: 21 }, //'21' though tagged as "b"
6: "={{ a }}+{{ b }}" //forumla adding row3,col4 with row3,col5 => '=D3+E3'
}
});
`
Note: cell a and b are looked up on send()

#### API


##### Spreadsheet.load( options, callback( err, spreadsheet ) )

See Options below

##### spreadsheet.add( obj | array )
Add cells to the batch. See examples.

##### spreadsheet.send( [options,] callback( err ) )
Sends off the batch of add()ed cells. Clears all cells once complete.

options.autoSize When required, increase the worksheet size (rows and columns) in order to fit the batch - NOTE: When enabled, this will trigger an extra request on every send() (default false).

##### spreadsheet.receive( [options,] callback( err , rows , info ) )
Recieves the entire spreadsheet. The rows object is an object in the same format as the cells you add(), so add(rows) will be valid. The info object looks like:

`
{
spreadsheetId: 'ttFmrFPIipJimDQYSFyhwTg',
worksheetId: 'od6',
worksheetTitle: 'Sheet1',
worksheetUpdated: '2013-05-31T11:38:11.116Z',
authors: [ { name: 'jpillora', email: 'dev@jpillora.com' } ],
totalCells: 1,
totalRows: 1,
lastRow: 3
}
`

options.getValues Always get the values (results) of forumla cells.

##### spreadsheet.metadata( [data, ] callback )

Get and set metadata

*Note: when setting new metadata, if rowCount and/or colCount is left out,
an extra request will be made to retrieve the missing data.*

##### spreadsheet.raw

The raw data recieved from Google when enumerating the spreedsheet and worksheet lists, which are triggered when searching for IDs. In order to see this array of all spreadsheets (raw.spreadsheets) the spreadsheetName option must be used. Similarly for worksheets (raw.worksheets), the worksheetName options must be used.

#### Options

##### callback
Function returning the authenticated Spreadsheet instance.

##### debug
If true, will display colourful console logs outputing current actions.

##### username password
Google account - Be careful about committing these to public repos.

##### oauth
OAuth configuration object. See google-oauth-jwt. By default oauth.scopes is set to ['https://spreadsheets.google.com/feeds'] (https if useHTTPS)

##### accessToken
Reuse a generated access token of the given type. If you set accessToken to an object, reauthentications will not work. Instead use a function accessToken(callback(err, token)) { ... } function, to allow token generation when required.

##### spreadsheetName spreadsheetId
The spreadsheet you wish to edit. Either the Name or Id is required.

##### worksheetName worksheetId
The worksheet you wish to edit. Either the Name or Id is required.

##### useHTTPS
Whether to use https when connecting to Google (default: true)

##### useCellTextValues
Return text values for cells or return values as typed. (default: true)

#### Todo

* Create New Spreadsheets
* Read specific range of cells
* Option to cache auth token in file

#### FAQ

* Q: How do I append rows to my spreadsheet ?
* A: Using the info object returned from receive(), one could always begin add()ing at the lastRow + 1, thereby appending to the spreadsheet.
