Send Tweets from Google Sheets

It is possible to send bulk tweets from Google Spreadsheet using Google Scripts. To get started, you need to include the OAuth1 libarary in your project, create a new Twitter app on apps.twitter.com and pass the Consumer Keys and API Secret to the Google Script project.

function sendTweet(user, tweet, tweet_type) {

    var twitterService = getTwitterService_();

    // If the Google Apps user has authorized the Twitter service
    if (twitterService.hasAccess()) {

        // Remove @ from the Twitter user name, if found
        var twitterUser = user.trim().replace(/^\@/, "");

        var api = "https://api.twitter.com/1.1/";

        // Send a public @tweet or direct message (DM)
        if (tweet_type === "DM") {
            api += "direct_messages/new.json?screen_name=" + twitterUser + "&text=" + encodeString_(tweet);
        } else if (tweet_type === "TWEET") {
            tweet = "@" + twitterUser + " " + tweet;
            api = "statuses/update.json?status=" + encodeString_(tweet);
        }

        var response = twitterService.fetch(api, {
            method: "POST",
            muteHttpExceptions: true
        });
        if (response.getResponseCode() === 200) {
            Logger.log("Tweet sent");
        } else {
            Logger.log("ERROR: " + JSON.parse(response.getContentText()).errors[0].message);
        }
    }
}

// Google Script has trouble sending tweets that contain !*()'
// so we replace these variable from the status text
function encodeString_(q) {
    var str = q;
    str = str.replace(/!/g, 'Ị');
    str = str.replace(/\*/g, '×');
    str = str.replace(/\(/g, '[');
    str = str.replace(/\)/g, ']');
    str = str.replace(/'/g, '’');
    return encodeURIComponent(str);
}
