By the Google’s update at June 19, 2018, finally, Utilities.computeDigest(), Utilities.computeHmacSha256Signature() and Utilities.computeHmacSignature() got to be able to use the byte arrays. By this, using only native Google Apps Script, the result can be retrieved without using jsSHA. So Cryptopia API can be created using only Google Apps Script. If this is useful for you, I’m glad.

Sample script :

When you use this, at first, please input the requiring values. Now the sample values are used.

By this, using only native Google Apps Script, the result can be retrieved without using jsSHA. When I used the updated them, the response speed is much faster than that of jsSHA. It is considered that this may be optimized for Google Apps Script. As a sample, it shows 2 samples as follows. The both results are the same.

FilesApp is a GAS library for retrieving file and folder list in Google Drive using Google Apps Script (GAS). Also this can create a tree from all files and folders in Google Drive.

Description

When I create some applications using Google Drive, there are often the case which is required to retrieve the file list and folder list. I had prepared the script each time for each case so far. But recently, I thought that if there is a library for retrieving the file and folder list (as a tree), it will be useful for me and other developers. So I created this. If this was useful for your situation, I’m glad.

This sample script is for retrieving a key with the maximum value from an object. This can be also used by Google Apps Script.

var obj = {"a": 5, "b": 4, "c": 3, "d": 2, "e": 1};
var res = Object.keys(obj).reduce(function(a, c) {
    return obj[a] > obj[c] ? a : c;
});

Logger.log(res); // >>> a

Overview

This is a sample script for easily retrieving the reformatted scripts without comments in a project using Google Apps Script (GAS).

Description

When I create GAS script, if the format of script is not correct, the script editor lets me know about it. By this, I can find that the script editor and/or Google Drive checks the format of scripts. I had wished if I could use this function. Recently, I noticed an interesting function. A GAS project is created and when function myFunction() {Logger.log(this)} is run in the script, I noticed that all scripts in the project are included in this. Furthermore, when I saw the retrieved script, also I noticed that their scripts are reformatted and all comments are removed. In the case of Apps Script API, when the scripts are retrieved by the API, the retrieved script is the same to the original one. So I think that this will help users retrieve simply the reformatted GAS scripts, and such the reformatted scripts will be able to be used for the various situations.

Overview

This is a method for removing Third-party Apps with Account Access using a script.

Demo

Description

When users create a script in a project and run the script, if the methods which are required to use scopes are included, users have to authorize to use the scopes using the browser. By authorizing it, users can use the script. The authorized projects can be seen at Third-party Apps with Account Access. One day, I had a situation that it required to remove the authorization of project, because of the security. Third-party Apps with Account Access can be manually removed as you know. But at that time, I wanted to remove using a script. So I came up with this method.

This is a sample script for retrieving a folder tree using Node.js. In this sample, you can set the top of folder for the folder tree. In generally, the folder tree is created by retrieving folders from the top folder in order. For example, when Google Apps Script is used, the script becomes like this. But when Drive API is used for this situation, if there are a lot of folders in the top folder, a lot of APIs are required to be called. So in this sample, I have tried to create the folder tree by a small number of API calls as possible.

• At October 11, 2019, I published a Javascript library to to run the resumable upload for Google Drive. When this is used, the large file can be uploaded. You can also use this js library.

  • Resumable Upload of Multiple Files with Asynchronous Process for Google Drive

Overview

This is a sample script for uploading files with large size (> 50 MB) at Web Apps using Google Apps Script (GAS). The resumable upload method is used for uploading files. This script can be also applied to the script using gapi of javascript.

goodls was updated to v.1.0.2

• v1.0.2 (May 10, 2018)

  1. Files with large size has gotten to be able to be used.
     • In order to download files with large size (several gigabytes), files are saved by chunks.

The detail information and how to get this are https://github.com/tanaikech/goodls.

This sample script retrieves the difference elements between 2 dimensional arrays using Google Apps Script. In Google Apps Script, 2 dimensional arrays are often used at Google Docs and Google APIs. And from my recent report, it has already found that the process cost of filter() is the lowest in the other loop methods. So I use the script like this.

var ar1 = [["a1", "b1", "c1"], ["a2", "b2", "c2"], ["a3", "b3", "c3"], ["a4", "b4", "c4"], ["a5", "b5", "c5"]];
var ar2 = [["a2", "b2", "c2"], ["a5", "b5", "c5"], ["a1", "b2", "c3"]];

var res = ar1.filter(function(e) {return ar2.filter(function(f) {return e.toString() == f.toString()}).length == 0});

Logger.log(res); // [["a1","b1","c1"],["a3","b3","c3"],["a4","b4","c4"]]

For above script, when it changes from == 0 to > 0, the duplication elements can be retrieved as follows.
