[Fixed] Google Apps Script Web App HTML form file-input fields not in blob compatible format

After V8 runtime was released, there was a bug that when the file is sent from HTML form to Google Apps Script side using google.script.run, the file blob was the invalid data.

From Apps Script Pulse by Martin Hawksey, it was found that the invalid blob of sending the file of HTML form to Google Apps Script side using google.script.run has finally been resolved. In this case, this script can be used with V8 runtime.

Retrieving Data from Content-Type of 'text/event-stream' using Javascript and Google Apps Script

Gists

This is a sample script for retrieving the data from Content-Type of ’text/event-stream’ using Javascript and Google Apps Script.

In the current stage, UrlFetchApp of Google Apps Script cannot be retrieved the data from Content-Type of ’text/event-stream’. This sample script can be used for achieving this as a workaround.

This sample script uses EventSource. So this script uses a dialog on Google Docs files (This sample uses Google Spreadsheet.).

Usage

1. Prepare Spreadsheet.

Create new Google Spreadsheet.

Pseudo OnEdit Trigger for Google Document using Google Apps Script

This is a sample script for achieving the pseudo OnEdit trigger for Google Document using Google Apps Script.

In the current stage, there is not OnEdit trigger for Google Document. Ref But I sometimes have the case that I want to use OnEdit trigger. So, as the current workaround, I created this sample script. I think that this workaround can be also used for Google Slides, Google Form and also Google Spreadsheet. In the case of Spreadsheet, what the existing OnEdit trigger and the time-driven trigger cannot do can be achieved.

Converting Range ID to Range Object on Google Spreadsheet using Google Apps Script

Gists

This is a workaround for converting the range ID to the range object on Google Spreadsheet using Google Apps Script.

When the named range is put to a cell as the hyperlink as follows,

Converting Range ID to Range Object on Google Spreadsheet using Google Apps Script

the hyperlink is like #rangeid=123456789. When this link is clicked, it moves to the cells of the named range. So it is considered that this value of #rangeid=123456789 includes the information about the range of the named range. But, unfortunately, in the current stage, there is no methods for directly retrieving the range object from the range ID. In this sample sample script, as a workaround, the range ID is converted to the range object using Google Apps Script.

Gists

This is a sample script for exporting all thumbnail images retrieved from Google Slides as a zip file using Google Apps Script.

Sample script

Before you use this script, please enable Slides API at Advanced Google services. Ref

function myFunction() {
  const presentationId = "###"; // Please set Google Slides ID.
  const folderId = "###"; // Please set the folder ID.
  const outputFilename = "###"; // Please set the output filename.

  const blobs = SlidesApp.openById(presentationId)
    .getSlides()
    .map((e, i) =>
      UrlFetchApp.fetch(
        Slides.Presentations.Pages.getThumbnail(
          presentationId,
          e.getObjectId(),
          {
            "thumbnailProperties.mimeType": "PNG",
            "thumbnailProperties.thumbnailSize": "LARGE",
          }
        ).contentUrl
      )
        .getBlob()
        .setName(`page${("000" + (i + 1)).slice(-3)}.png`)
    );
  DriveApp.getFolderById(folderId).createFile(
    Utilities.zip(blobs).setName(outputFilename + ".zip")
  );
}

Updated: Javascript library - ResumableUploadForGoogleDrive_js

ResumableUploadForGoogleDrive_js was updated to v2.0.0.

  • v2.0.0 (November 15, 2021)

    1. New Class ResumableUploadToGoogleDrive2 was added. By this, the large file which is over the memory in the local PC can be uploaded by the resumable upload.

Overview

This is a Javascript library to achieve the resumable upload for Google Drive.

Description

When a file more than 5 MB is uploaded to Google Drive with Drive API, the resumable upload is required to be used. I have already published the sample script for “Resumable Upload for Web Apps using Google Apps Script”. Ref In this case, Web Apps is used. Here, I would like to introduce the script for the resumable upload created by only Javascript. Unfortunately, in the current stage, at google-api-javascript-client, there are no methods for the resumable upload. And, I thought that when this function is created as a Javascript library, it might be useful for users. Also that library is also useful for me. So I created this. If this was useful for your situation, I’m glad.

Gists

This is a sample workaround for letting users running Google Apps Script on Google Spreadsheet without both authorizing the scopes and showing the script.

    • Your script can be included in this script.
  2. User put a formula of =IMPORTML("WebApps URL", "xpath") to a cell.

By this flow, you can achieve to let users running Google Apps Script on Google Spreadsheet without both authorizing the scopes and showing the script.

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.
