IMPORTANT: reduceRight with and without v8 runtime for Google Apps Script

Gists

This is an important point for using reduceRignt with and without v8 runtime for Google Apps Script.

Sample script

function myFunction() {
  var array = ["a", "b", "c", "d", "e"];
  var res = array.reduceRight(function (ar, e, i) {
    ar.push([e, i]);
    return ar;
  }, []);
  Logger.log(res);
}

Result

With V8

When V8 runtime is used, the following result is obtained.

[["e",4],["d",3],["c",2],["b",1],["a",0]]

Without V8

When V8 runtime is NOT used, the following result is obtained.

[["e",0],["d",1],["c",2],["b",3],["a",4]]

Summary

When above results are compared, it is found that the indexes are different. The indexes of “With V8” is in the opposite direction to that of “Without V8”. Please be careful this.

GAS Library - GASProjectApp

Overview

This is a Google Apps Script library for creating, updating and exporting Google Apps Script project of the standalone type using Drive API. In this case, Apps Script API is not used.

Description

I had reported “Drive API cannot create Google Apps Script project no longer” before. Ref About this, I had reported the future request. Ref At July 30, 2020, I could confirm that the Google Apps Script project of the standalone type got to be able to be created by multipart/form-data using Drive API again. Ref This is a good news for me. By this, in order to use this with Google Apps Script, I created this library. Because in this case, when the update method is used, the special scope of https://www.googleapis.com/auth/drive.scripts is required. So I thought that when this is published as the Google Apps Script library, this will be useful for users.

Drive API got to be able to create Google Apps Script project again

Gists

I have reported “Drive API cannot create Google Apps Script project no longer”. Ref About this, I had reported the future request. Ref Today, I could confirm that the Google Apps Script project of the standalone type got to be able to be created by multipart/form-data using Drive API. This is a good news for me. By this, the following 2 patterns can be used from now.

Pattern 1:

  1. Create new standalone GAS project by Apps Script API.
  2. Put the local script to the created GAS project by updating the project with Apps Script API.
  3. Move the GAS project from the root folder to the specific folder using Drive API.

In this pattern, 3 API calls are required.

Uploading Files of multipart/form-data to Google Drive using Drive API with Node.js

Gists

These are the sample scripts for uploading files of multipart/form-data to Google Drive using Drive API with Node.js. In this case, googleapis for Node.js is not used.

In these sample script, the maximum file size is 5 MB. Please be careful this. When you want to upload the files more than 5 MB, please check this report.

Sample script 1

This sample script uploads a file using the modules of fs and request. Before you use this script, please prepare your access token for uploading the file.

Workaround: Showing Log in Web Apps to Apps Script Dashboard using Javascript

Gists

I have already reported for showing the log to “Apps Script Dashboard” when it requests to the Web Apps. Ref In order to show the log to “Apps Script Dashboard” when it requests to the Web Apps, it is required to use the access token. But in the current stage, when the access token is used for XMLHttpRequest and fetch of Javascript in the request headers, the error related to CORS occurs. So, in this report, I would like to propose the workaround for resolving this issue.

Switching Buttons for Google Spreadsheet using Google Apps Script

Gists

These are the sample scripts for achieving the switching buttons for Google Spreadsheet using Google Apps Script. The management of images using Spreadsheet service is growing now. But, in the current stage, in order to achieve the switching buttons, it needs a little ingenuity. In this report, I would like to introduce 4 kinds of the switching buttons.

Pattern 1

In this pattern, the drawing is used as the button.

Using Request Body of String JSON for Google APIs with googleapis of golang

Gists

This is a sample script for directly using the request body of the string JSON for Google APIs with googleapis of golang.

At googleapis for golang, when Google API is used, it is required to create the request body like this sample script. I have several contacts for creating about such request body. I thought that such script might be a bit difficult for users. I thought that when the string JSON object is directly used for this, it might be useful. So I would like to introduce about this. When this was useful for your situation, I’m glad.

Converting SVG Format to PNG Format using Google Apps Script

Gists

This is a sample script for converting the SVG image data to PNG image data using Google Apps Script.

Unfortunately, in the current stage, there are no methods for directly converting the SVG to PNG in Google Drive service. But it can be achieved by Drive API. The sample script is as follows.

Before you use this, please enable Drive API at Advanced Google services.

Sample script

function myFunction() {
  const svgFileId = "###"; // Please set the fileId of the SVG file.

  const url = Drive.Files.get(svgFileId).thumbnailLink.replace(
    "=s220",
    "=s1000"
  );
  const blob = UrlFetchApp.fetch(url).getBlob(); // blob is the image blob of PNG format.

  // In this sample, the retrieved image blob is put to Spreadsheet.
  const sheet = SpreadsheetApp.openById("###").getSheetByName("Sheet1");
  sheet.insertImage(blob, 1, 1).setWidth(500).setHeight(500);
}
  • In this sample script, the converted PNG image is put to the Spreadsheet.

This specialized developer utility is designed to research, benchmark, and optimize advanced integrations between Google Workspace services, the Google Apps Script API, and Gemini AI models (via Google Vertex AI / Gemini API endpoints).

The application facilitates automated multi-agent scaffolding, programmatic script deployment, project resource management, and structural analysis of Google Apps Script projects. It allows developers and autonomous AI agents (operating via Model Context Protocol / MCP) to securely evaluate execution performance, implement high-performance batch requests, and test agent-to-agent (A2A) workflows within a controlled and structured environment.

Google User Data Policy Compliance Statements:

1. Data Access & Specific Usage

Our application explicitly requests access to specific Google user accounts through OAuth scopes required strictly for interacting with the Google Apps Script API and Google Workspace endpoints. This access is utilized solely to execute user-initiated or agent-orchestrated programmatic operations—such as creating, modifying, deploying, or benchmarking script projects and executing automated workflows. No background automated extraction occurs without explicit session initiation.

2. Data Storage & Zero-Retention Policy

Adhering to a strict Zero-Retention Model, this application does not store, log, or persist any personal data, OAuth tokens, script source codes, or Google account configurations on any external server, database, or persistent storage medium. All data processing and API responses are handled entirely in-memory or securely on the client side within the active session context, ensuring complete cryptographic transient isolation.

3. Data Sharing & Third-Party Non-Disclosure

We maintain absolute data privacy. No data accessed via Google OAuth scopes is shared, sold, rented, or transferred to third-party entities, advertising networks, or data brokers.
