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

Image by Tumisu from Pixabay

HTML form file-input fields are not converted to compatible blob format when submitted. They are left in application/octet-stream format. The file-input fields are passed as application/octet-stream, so DriveApp.createFile(formBlob) does not work correctly … So the functionality provided by HtmlService is not consistent with the documentation

There was an annoying little Google Apps Script issue which meant when handling file uploads to published Web Apps some additional coding was required rather than just sending the file blob server side. Thankfully the open issue ticket for this has recently been marked and confirmed fixed.

Letting users run a Google Apps Script on Google Sheets without authorizing scopes and showing the source code

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

The post highlights the use of the existing =IMPORTML() Google Sheets function and a publish webapp to run a Google Apps Script without the end user having to authorize the script. A limitation of this approach, and also important warning to keep in mind, is the deployed web app needs to be deployed to run as the script owner and by anyone who has the web app link.

Keep a Journal of Special Moments using Twilio Programmable SMS and Google Sheets

Learn how to build a Google Sheet journal that accepts new entries via text message. My toddler recently turned two and a half and my second daughter was born three weeks ago, so special moments are abundant but the ability to remember them is severely compromised. His suggestion of recording a memory every day in an Excel sheet or leather bound journal resonated with me, but after a few days of trying to find time to open up Excel and write a memory I realized I needed a more lightweight solution. … Twilio makes it easy and cheap to set up a dedicated phone number that can record those text messages to a Google sheet.

Nice example on the Twilio blog on using their service with Google Sheets. There is little setup required but this can all be achieved in 4 lines of code. Unfortunately, sending/receiving SMS messages with Twilio is not free, but it might be a service you keep in mind for Apps Script projects.

Creating a web app with Google Sheets

Using Google Apps Script as a Webhook

Google Apps Script projects can be published as web apps …. This is helpful if you’re building a tool with a simple UI (using HTMLService), but they can also be used as webhooks to do work within a user account.

Google provides the option of service accounts, so why use webhooks?

For my project, it was because I needed to send calendar invites to other people. Service accounts are generally the way to handle those kinds of jobs, but it needed to have full account delegation, which means it can act on behalf of any user in the domain. That wasn’t an option in this case, so a webhook became the next best option.

Brian Bennett highlights the benefits of using ContentService and Web Apps as a way to let you interface other services.

Tracking Google Sheet Opens with Google Apps Script

The basic principle behind tracking Google Sheet opens is the same as the one behind email tracking with a transparent pixel.

The web app will be able to do whatever you need among the following: record to a spreadsheet, create a message via a messenger, or simply send an email.

XPath Tester using Web Apps Created by Google Apps Script (working with existing Google Sheets functions in Apps Script)

This is an interesting little Apps Script solution from Kanshi Tanaike which uses the existing Google Sheets =IMPORTXML() in a Google Apps Script  Web App to test an XPath. As there is a delay in loading some Google Sheets function results this post includes a nice little coding pattern using a do...while loop to wait for results to render.

Make your own Office Desk Booking with Apps Script

In this new era post Covid, to come back to work we have to maintain a certain quota of people at the office. At Devoteam G Cloud we had this needs and to be able to manage people at office we build a web app with Apps Script to manage team and people presence on site.

A great example from Stéphane Giron using Google Apps Script to rapidly develop and deploy an office management solution. The post highlights the utility of PropertiesService to store data in the web app. This solution falls into the category of minimum viable product, but given the nature of Apps Script could be a great project to build on with integration with other Google services.
