Enriched Management of Rich Text on Google Spreadsheet using Google Apps Script

In the current stage, Google Spreadsheet can use rich texts in cells. The rich texts can be also managed by Google Apps Script. But, I thought that creating a script for editing the existing rich text in the cell might be a bit complicated. Because, for example, in the current stage, when the text of the rich text of a cell is changed using a script, all text styles are cleared. In order to add and delete a text for the rich text in a cell, it is required to create a script while the current text style is kept. This is actually complicated. In this post, I would like to introduce the enriched management of rich text on Google Spreadsheet using Google Apps Script. In order to enrich the management of Rich Text using Google Apps Script, I created a library RichTextAssistant.

GAS Library - RichTextAssistant

GAS Library - RichTextAssistant

Overview

This is a GAS library for supporting editing RichText in Google Spreadsheet using Google Apps Script.

Description

There is RichTextApp in my published libraries. RichTextApp can be used mainly for converting RichText to Google Documents and vice versa. This library RichTextAssistant will support editing the rich text in Google Spreadsheets using Google Apps Script. Google Spreadsheet can use rich text as the cell value using Google Apps Script. But, I thought that when I created a script for editing the existing rich text in the cell, it might be a bit complicated. Because, for example, in the current stage, when the text of rich text of a cell is changed using a script, all text styles are cleared. In order to add and delete a text for the rich text in a cell, it is required to create a script while the current text style is kept. This is actually complicated. From this situation, when a script for supporting editing the rich text in a cell is published, it will be useful for a lot of users. So, I created it and published it as “RichTextAssistant” of a Google Apps Script library.

Benchmark: Process Costs for Searching Value using Object with Google Apps Script

Gists

When a value is searched from the 1-dimensional array and a 2-dimensional array, after V8 runtime could be used, I use JSON object, Set object, and Map Object. But, I had never measured the process cost of this situation. In this post, I would like to introduce the process cost for searching a value using a JSON object, Set object, and Map object converted from the 1-dimensional array and 2-dimensional array.

Importing Microsoft Excel to Google Spreadsheet using Custom Function with Google Apps Script

Importing Microsoft Excel to Google Spreadsheet using Custom Function with Google Apps Script

This is a sample script for importing Microsoft Excel (XLSX) data to Google Spreadsheet using a custom function with Google Apps Script.

Usage

1. Install SheetJS library.

Please copy the script of the SheetJS library from https://cdn.sheetjs.com/xlsx-latest/package/dist/xlsx.full.min.js, and paste the script to the script editor of Google Spreadsheet, and save the script.

In this case, I would like to recommend the following flow.

Directly Retrieving Values from XLSX data using SheetJS with Google Apps Script

Gists

Updated on July 8, 2023

In the current stage, unfortunately, the built-in methods of Google Apps Script cannot directly retrieve the values from the XLSX data. From this situation, I have created DocsServiceApp. When this Google Apps Script library is used, the values are directly retrieved from XLSX data by parsing XML data of XLSX data.

Here, as another approach, I would like to introduce a sample script for directly retrieving the values from XLSX data using SheetJS with Google Apps Script. In the current stage, Google Apps Script can run with V8 runtime. By this, it seems that SheetJS can be used.

Split Binary Data with Search Data using Google Apps Script

Gists

This is a sample script for splitting the binary data with search data using Google Apps Script.

Sample script

/**
 * Split byteArray by a search data.
 * @param {Array} baseData Input byteArray of base data.
 * @param {Array} searchData Input byteArray of search data using split.
 * @return {Array} An array including byteArray.
 */
function splitByteArrayBySearchData_(baseData, searchData) {
  if (!Array.isArray(baseData) || !Array.isArray(searchData)) {
    throw new Error("Please give byte array.");
  }
  const search = searchData.join("");
  const bLen = searchData.length;
  const res = [];
  let idx = 0;
  do {
    idx = baseData.findIndex(
      (_, i, a) => [...Array(bLen)].map((_, j) => a[j + i]).join("") == search
    );
    if (idx != -1) {
      res.push(baseData.splice(0, idx));
      baseData.splice(0, bLen);
    } else {
      res.push(baseData.splice(0));
    }
  } while (idx != -1);
  return res;
}

// Please run this function.
function main() {
  const sampleString = "abc123def123ghi123jkl";
  const splitValue = "123";

  const res1 = splitByteArrayBySearchData(
    ...[sampleString, splitValue].map((e) => Utilities.newBlob(e).getBytes())
  );
  const res2 = res1.map((e) => Utilities.newBlob(e).getDataAsString());

  console.log(res1); // [[97,98,99],[100,101,102],[103,104,105],[106,107,108]]
  console.log(res2); // ["abc","def","ghi","jkl"]
}
  • When main() is run, the sample input values of "abc123def123ghi123jkl" is split by "123". And, [[97,98,99],[100,101,102],[103,104,105],[106,107,108]] is obtained. In this case, when [[97,98,99],[100,101,102],[103,104,105],[106,107,108]] is converted to the string for confirming the result value, it becomes ["abc","def","ghi","jkl"].

Exporting Google Docs Files in PDF format with Batch Requests using Google Apps Script

Gists

This is a sample script for exporting Google Docs files (Spreadsheets, Documents, and so on) in PDF format with batch requests using Google Apps Script.

I have published a report “Efficient File Management using Batch Requests with Google Apps Script”. In this report, I mentioned how to use the batch requests using Google Apps Script.

In this post, I would like to introduce the method for retrieving binary data using this method.

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).
