  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const [srcSheet, dstSheet] = [srcSheetName, dstSheetName].map((s) =>
    ss.getSheetByName(s)
  );
  const [head, ...values] = srcSheet.getDataRange().getValues();
  const res = [
    head,
    ...values.flatMap((r) => {
      const { v, max } = expandedColumns.reduce(
        (o, c, i) => {
          const s = r[c - 1].split(delimiter);
          o.v[c - 1] = s;
          const len = s.length;
          if (i == 0) {
            o.max = len;
          } else {
            o.max = o.max > len ? o.max : len;
          }
          return o;
        },
        { v: {}, max: 0 }
      );
      return [...Array(max)].map((_, j) =>
        r.map((c, k) => (!v[k] ? c : v[k][j] || null))
      );
    }),
  ];
  dstSheet.getRange(1, 1, res.length, res[0].length).setValues(res);
}
  • When this script is run, the above sample situation can be obtained.
  • For example, when you change const expandedColumns = [2, 3, 4, 5]; to const expandedColumns = [5];, only the column “E” is expanded.

Number of Requests for Sheets API using Google Apps Script

Gists

This is a report for checking the number of requests for Sheets API. I had contact about the quota for Sheets API. So, in order to explain this, I used the following simple sample scripts.

Sample 1

This sample puts a value of “sample” to a cell “A1” using the batchUpdate method. This request body includes one request. When this script is run, one API quota is used.

function sample1() {
  const spreadsheetId = "###";
  const sheetId = 0;

  const requests = [{
    "updateCells": {
      "rows": [
        {
          "values": [
            {
              "userEnteredValue": {
                "stringValue": "sample"
              }
            }
          ]
        }
      ],
      "range": {
        "sheetId",
        "startRowIndex": 0,
        "endRowIndex": 1,
        "startColumnIndex": 0,
        "endColumnIndex": 1
      },
      "fields": "userEnteredValue.stringValue"
    }
  }];
  Sheets.Spreadsheets.batchUpdate({ requests }, spreadsheetId);
}

Sample 2

This sample puts 1000 values like “sample#” to the cells of “B1:B1000” using the batchUpdate method. This request body includes 1000 requests. When this script is run, one API quota is used.

Increasing Column Letter by One using Google Apps Script

Gists

This is a sample script for increasing the column letter by one using Google Apps Script.

Sample script

const increase = (ar) =>
  ar.map((e) => {
    const idx = [...e].reduce(
      (c, e, i, a) =>
        (c += (e.charCodeAt(0) - 64) * Math.pow(26, a.length - i - 1)),
      -1
    );

    // Ref: https://stackoverflow.com/a/53678158
    columnIndexToLetter = (n) =>
      (a = Math.floor(n / 26)) >= 0
        ? columnIndexToLetter(a - 1) + String.fromCharCode(65 + (n % 26))
        : "";

    return columnIndexToLetter(idx + 1);
  });

const samples = ["A", "Z", "AA", "AZ", "ZZ"];
const res = increase(samples);
console.log(res); // <--- [ 'B', 'AA', 'AB', 'BA', 'AAA' ]
  • When this script is used, the column letters of ["A", "Z", "AA", "AZ", "ZZ"] is increased by one. As the result, [ 'B', 'AA', 'AB', 'BA', 'AAA' ] is obtained.

GAS Library - DocNamedRangeApp

Overview

GAS Library - DocNamedRangeApp

This is a Google Apps Script library for managing the named range on Google Documents.

Description

Google Document can use the named range. When the named range is used, the users can directly access the contents using the named range. For example, the developer can guide the users to the specific content in Google Documents using the named range. But, unfortunately, in the current stage, it seems that the named range cannot be directly used by the UI on Google Documents. It is required to use Google Apps Script. But, I thought that when I saw the official document of the named range, it might be difficult to understand it. Ref So, I created this library. When this library is used, the named ranges on Google Documents can be managed.

Introduction

On March 14, 2022, it reported about “Google Sheets doubles cell limit”. Ref By this update, now, the users can use 10,000,000 cells in a Google Spreadsheet. This is great news for us. When I tried to handle 10,000,000 cells in a Google Spreadsheet using Google Apps Script, it was found that there were various important points. In this report, I would like to introduce the important points for handling 10,000,000 cells in Google Spreadsheet using Google Apps Script.

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).
