Sample Array Script for Spreadsheet

This is a Sample Array Script for Spreadsheet. It makes an 2D array filled by strings and number. The strings and number are column strings and row number, respectively.

However, because this is a sample, the maximum column number is 26.

function sa(row, col){
  if (col > 26) return;

  var ar = new Array(row);
  for(var i = 0; i < row; i++) ar[i] = new Array(col);
  for (var i = 0; i < row; i++){
    for (var j = 0; j < col; j++){
      ar[i][j] = String.fromCharCode(i + 97) + String(j + 1);
    }
  }
  return ar.map(function(x, i){return x.map(function(y, j){return ar[j][i]})});
}

When “sa(10,10)” is given, following array can be output.

Event of onEdit() for Google spreadsheet

About Event Objects

For example, it thinks the situation of input text of ’test’ to ‘A1’ on a sheet.

When you use only ‘onEdit(e)’ without an installing trigger, ’e’ has following parameters.

{authMode=LIMITED, range=Range, source=Spreadsheet, user=, value=test}

In this case, the event cannot send an e-mail because of ‘authMode=LIMITED’.

When you use “onEdit(e)” with an installing trigger of “Edit”, ’e’ has following parameters.

{authMode=FULL, range=Range, source=Spreadsheet, value=test, triggerUid=#####}

In this case, the event can send an e-mail because of ‘authMode=FULL’.

File upload using doPost on Google Web Apps

File upload using HTML form in GAS project

Rule

Following scripts have to be made into a project of Google Apps Script.
Deploy the GAS project as a web application. Ref
After updated the script, it has to be updated as a new version.

Form.html :

<html>
  <body>
    <form>
      <input type="file" name="imageFile">
      <input type="button" value="ok" onclick="google.script.run.upload(this.parentNode)">
    </form>
  </body>
</html>

GAS :

function doGet() {
  return HtmlService.createHtmlOutputFromFile('Form.html');
}

function upload(e) {
  var destination_id = '#####'; // Folder ID of destination folder

  // Reference : https://developers.google.com/apps-script/reference/base/blob#getAs(String)
  // You can use 'application/pdf', 'image/bmp', 'image/gif', 'image/jpeg' and 'image/png'.
  var contentType = 'image/jpeg';
  var img = e.imageFile;

  var destination = DriveApp.getFolderById(destination_id);
  var img = img.getAs(contentType);
  destination.createFile(img);
}

When you set ‘image/jpeg’ as “contentType” and upload png file, the uploaded image file is converted to jpeg file and saved it to the destination folder.

One Liner Code for Netatmo

I made One Liner Code to retrieve data using Netatmo API. There are 2 ways. One is for windows dos. Another is for unix bash. Requirement tools are curl and jq.

windows dos

> setlocal & curl -s -d "grant_type=password&client_id='#####'&client_secret='#####'&username='#####'&password='#####'&scope=read_station" "https://api.netatmo.net/oauth2/token" | for /f "usebackq tokens=*" %a in (`jq -r ".access_token"`) do @set a="%a" | curl -s -d "access_token=%a&device_id='#####'" "https://api.netatmo.net/api/getstationsdata" > dat.txt & for /f "usebackq tokens=*" %b in (`jq -r ".body.devices[0].dashboard_data.Temperature" dat.txt`) do @set b="%b" | echo: & set /p nb=Indoor: Temperature %b [degree C],<nul & for /f "usebackq tokens=*" %b in (`jq -r ".body.devices[0].dashboard_data.Humidity" dat.txt`) do @set b="%b" | set /p nb=Humidity %b [%],<nul & for /f "usebackq tokens=*" %b in (`jq -r ".body.devices[0].dashboard_data.Pressure" dat.txt`) do @set b="%b" | set /p nb=Pressure %b [hPa]<nul & for /f "usebackq tokens=*" %b in (`jq -r ".body.devices[0].modules[0].dashboard_data.Temperature" dat.txt`) do @set b="%b" | echo: & set /p nb=Outdoor: Temperature %b [degree C],<nul & for /f "usebackq tokens=*" %b in (`jq -r ".body.devices[0].modules[0].dashboard_data.Humidity" dat.txt`) do @set b="%b" | set /p nb=Humidity %b [%]<nul & del dat.txt

Indoor: Temperature 12 [degree C],  Humidity 56 [%],  Pressure 1000.2 [hPa]
Outdoor: Temperature 12.3 [degree C],  Humidity 56 [%]

unix bash

$ curl -s -d "grant_type=password&client_id='#####'&client_secret='#####'&username='#####'&password='#####'&scope=read_station" "https://api.netatmo.net/oauth2/token"|curl -s -d "access_token=`jq -r '.access_token'`&device_id='#####'" "https://api.netatmo.net/api/getstationsdata"|jq -r '"\nIndoor: Temperature "+(.body.devices[0].dashboard_data.Temperature|tostring)+" [degree C], Humidity "+(.body.devices[0].dashboard_data.Humidity|tostring)+" [%], Pressure "+(.body.devices[0].dashboard_data.Pressure|tostring)+" [hPa]\nOutdoor: Temperature "+(.body.devices[0].modules[0].dashboard_data.Temperature|tostring)+" [degree C], Humidity "+(.body.devices[0].modules[0].dashboard_data.Humidity|tostring)+" [%]"'

Indoor: Temperature 12 [degree C], Humidity 56 [%], Pressure 1000.2 [hPa]
Outdoor: Temperature 12.3 [degree C], Humidity 56 [%]

If you want to use these One Liner Codes, you can use following code. Please replace “#####” to yours.

This “souwapy” is a library for summing array elements with high speed by new algorithm (Pyramid method). The speed is faster than csv and panbdas module of python and v8 engine of node.js. The souwapy module is 2.3 and 3.1 times faster than csv and pandas module, respectively. This was really surprised me. It was found that the theory was correct.

At first, I have created this theory for Google Apps Script. But recently I had to use large data and output a csv file on python. So I made this library. Additionally, I had wanted to know how to public own library to PyPI before. This chance was good for me. If this library is helpful for other people, I’m glad.

Element's Duplicate Number in Array at Python

Suddenly I had to need this.

This script can get the duplicate number of each element in array at Python. In this script, the duplicate number of each element is obtained and sorted by the duplicate number. This was expressed by the comprehension.

data = ['a', 'b', 'c', 'd', 'b', 'c', 'd', 'b', 'c', 'b']
result = sorted({i: data.count(i) for i in set(data)}.items(), key=lambda x: x[1], reverse=True)
print(result)

>>> [('b', 4), ('c', 3), ('d', 2), ('a', 1)]

CoffeeScript

I may be slow a bit, but I could notice much convenience of CoffeeScript just now. I didn’t know that scripts of GAS can be made by CoffeeScript up until now. This will have me work more effectively! :D

Google OAuth Verification & Application Privacy Policy

Registered Application Name: Workspace & Gemini AI Orchestration Engine

Application Purpose & Core Functionality:

This web page serves as the official homepage and privacy compliance interface for the application "Workspace & Gemini AI Orchestration Engine". 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. All data transmissions are strictly point-to-point, encrypted in transit using industry-standard protocols, and limited entirely to the direct channel between the execution environment and Google's official API gateways.

For inquiries regarding this developer application, technical benchmarks, or verification compliance, please refer to the official documentation and repositories linked on this homepage (tanaikech.github.io).
