Uploading CSV File as Spreadsheet and Modifying Permissions using Golang

Gists

This sample script is for uploading CSV file as Spreadsheet and modifying permissions using Golang.

I think that the detail information of google-api-go-client is a bit little. The sample scripts are so little. It retrieves most information from only godoc and GitHub. So I publish such sample scripts here. If this is useful for you, I’m glad.

Important points :

  1. Give mimeType of file that it wants to upload to options of Media(r io.Reader, options ...googleapi.MediaOption).
  2. In order to give options, use googleapi.ContentType().
  3. Give mimeType of file that it wants to convert, when it uploads it to Google Drive, to file of Create(file *File).
  4. In order to give file, use &drive.File{}.
  5. For installing permissions, use &drive.Permission{}. Each parameter is the same to them for Python.

This sample script uses Quickstart. So in order to use this sample script, at first, please do Step 1 and Step 2 of the Quickstart.

Selecting Files in Google Drive using Select Box for Google Apps Script

Gists

This is a sample script for selecting files in Google Drive using HTML select box for Google Apps Script.

Feature

Feature of this sample.

  • It is a simple and space saving.
  • When the folder is selected, the files in the folder are shown.
  • When the file is selected, the ID of file is retrieved. Users can use this ID at GAS.
  • When a folder is opened, all files in the folder are cached. By this, the second access of the folder is faster.
  • It doesn’t retrieve all files in Google Drive at once, so the read of files from Google Drive becomes the minimum necessary.

I will use this for applications that users need to select files on Google Drive.

You can see MajorDimension, Range and Values in ValueRange.

Updated ggsrun to v131

ggsrun was updated to v.1.3.1

  1. Recently, when scripts on local PC is uploaded to Google Drive as a new project, the time to create on Google became a bit long. (I think that this is due to Google Update.) Under this situation, when the script is uploaded, the timeout error occurs while the new project is created using the script. So the time until timeout of fetch was modified from 10 seconds to 30 seconds. By this, when the script is uploaded, no error occurs and the information of the created project is shown.
    • You can create a new project on Google Drive using scripts on local PC. The sample command is ggsrun u -f sample.gs1,sample2.gs,sample3.html -pn newprojectname

You can check this and download ggsrun at https://github.com/tanaikech/ggsrun.

Uploading Image Files to Slack Using Incoming Webhooks by Google Apps Script

Gist

This sample script is for uploading image files to Slack using Incoming Webhooks by Google Apps Script.

When users try to upload image files to Slack using Incoming Webhooks, it has been known that although the access token is required to directly upload them, Incoming Webhooks can upload them by using the tag of image_url. In this sample script, it uploads image files (BMP, GIF, JPEG and PNG) on Google Drive to Slack using Incoming Webhooks. The script is written by Google Apps Script.

Retrieving Files with Filename Included Special Characters using Google Apps Script

Gists

This sample script is for retrieving files with filename included special characters using Google Apps Script. The files are used on Google Drive.

The files with filename of special characters cannot be retrieved using DriveApp.getFilesByName(). This workaround solved this.

As a query parameter, name contains 'filename with special characters' is used. This contains is very important. name='filename with special characters' cannot retrieve such files. Today, it was found that name contains 'filename with special characters' is the workaround. I have been looking for this workaround for a while. Finally, I found this today. By using this method, filename included umlauts can be also retrieved.

Removing Duplicated Values in Array using CoffeeScript

Gists

This sample script is for removing duplicated values in array using CoffeeScript.

ar = ["a", "b", "c", "a", "c"]
res = ar.filter (e, i, s) -> s.indexOf(e) is i
console.log res

>>> [ 'a', 'b', 'c' ]

The result which was compiled by CoffeeScript is as follows.

var ar, res;
ar = ["a", "b", "c", "a", "c"];
res = ar.filter(function(e, i, s) {
  return s.indexOf(e) === i;
});
console.log(res);

Retrieving Spreadsheet ID from Range using Google Apps Script

Gists

This is a sample script for retrieving spreadsheet ID from a range using Google Apps Script. I sometimes want to retrieve spreadsheet ID from ranges. In such case, I always use this.

  • Range
  • -> Retrieve Sheet using getSheet()
  • -> Retrieve Spreadsheet using getParent()
  • -> Retrieve spreadsheet ID
var id = "123456789abcdefg";
var sheet = "Sheet";
var cells = "a1:b10";
var range = SpreadsheetApp.openById(id).getSheetByName(sheet).getRange(cells);

var id = range.getSheet().getParent().getId();

>>> id ---> 123456789abcdefg

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).
