Google Spreadsheet Object API (Node.js)

This is Node.js module for creating Sheet objects that can fetch or push data to online Google Sheets.

• Local changes - all data fetched or pushed at once to preserve order
• Ability to create new Spreadsheets

Coming soon:

• Methods for storing and pulling NoSQL databases
• Security features

Installation

Dependencies:

• Node "async"

Instructions:

• Move the folder into your work directory

• Copy the files in the "Google Apps" folder into a Google Apps Script

• Publish the Google Apps Script as yourself with anonymous access

• Run node test.js to verify functionality

Basic Usage

var GSheet = require('./googlesheets');
var async   = require('async');

var url = 'Google-App-Scripts-exec';
var ID = 'Spreadsheet-ID';
var name = 'Sheet-Name';

var sheet = new GSheet(url, ID, name);

// Create and send a sheet
sheet.setRow(0, ["a", "b", "c", "d"]);
sheet.setRow(1, ["1", "2", "3", "4"]);
sheet.setRow(2, ["A", "B", "C", "D", "E"]);
sheet.setRow(3, ["5", "6", "7"]);

console.log("\nOriginal Sheet:")
sheet.printSheet();
sheet.send();

// Get a sheet
var newSheet = new GSheet(url, ID, name);
async.series([
	function(step) {
		newSheet.getSheet(step);
	},
	function(step) {
		console.log("\nNew Sheet:")
		newSheet.printSheet();
		step();
	},
	function(step) {
		newSheet.setRow(5, ["8", "9"]);
		console.log("\nUpdated Sheet:");
		newSheet.printSheet();
		newSheet.send()
		step();
	}
]);

    Row 1: 1; 2; 3; 4;  ;
    Row 2: A; B; C; D; E;
    Row 3: 5; 6; 7;  ;  ;

• maxWidth - value for the max width

setRow(index, row)

Sets the row at the specified index in the spreadsheet

• index - integer index for the new row (overwrites if there is already a row at that index)

• row - array containing the values for the row

getRow(index)

Returns an array with the values of the specified row

• index - integer index for the new row

send()

Sends the spreadsheet to update the target

• index - integer index for the new row (overwrites if there is already a row at that index)

Sends the spreadsheet to a specified target, ignoring the object target

• ID - string containing the new ID

• name - string containing the new sheet name

get()
