Replace text in a Google Doc with an image

The following Google Apps Script is designed to search the body of a Google Doc for a specific string/pattern (i.e. a keyword) and insert an image in place of it, optionally making it a clickable hyperlink too.


In this example the code is designed to sit behind the Google Doc so it is bound to it. There are 4 pieces of information to complete in order to setup the script:

  1. searchText - this is the unique string/pattern in the Doc that you want to replace with an image e.g. "<<keyword>>"

  2. imageURL - this is the direct link to the image in Google Drive that you wish to use in the Doc.

  3. size - a numerical value representing the number of pixels for the image's width/height.

  4. hyperlinkURL - if you want the image to be clickable then provide a link for it.

Google Add-on: Form Calendar Invites

What it does

The Add-on allows you to link a Google Form™ with Google Calendar™ events so that when people complete the Form and select a particular title/date/time from it, they are sent an automated email invite to one of the respective Calendar events.

This allows you to have Calendar events with all guests attached to it such as for conferences, workshops, drop-ins, training sessions, etc. Therefore any changes to an event (description/conferencing, etc) will be reflected for all guests - just like any other event.

Sessions listed in the Form can be selected

Google Add-on: Convert Drive Files update December 2023


What it does

Bulk convert Google Drive™ files quickly and easily with this Add-on. Convert between Google™, Microsoft Office™, OpenDocument, PDF, etc. Point the Add-on at a Google Drive™ folder, select the file types you want to convert, select your destination folder and whether you want the original file to be deleted, then hit go! Saves having to go into each file individually, selecting the file type to download and then selecting the save destination.


  • Remove original file extension option
    • Based on feedback, the default behaviour for automatically removing any existing file extension has been stopped. There is now a simple Yes/No option allowing you to choose for yourself exactly what you want to happen. The main reason for this change was due to file names containing 'full stops' that would otherwise be lost as the tool treat them as part of the extension.

Control Form submissions with Script Lock

The following Google Apps Script is one example of how the Lock Service can be used to prevent concurrent running of code. Here we have a Google Form that can be submitted by users at any point, the code then takes some of those details and appends them to another Google Sheet row. In normal circumstances this will happen relatively quickly and without clashes, but what if multiple people submit the Form at the same time!?

The likelihood is that whilst the Form data will still be collected correctly in the response sheet, the append Sheet will either overwrite data as it tries to keep up or miss it completely. By using the Lock Service we can allow each Form submission time to complete its bit of code before the next one starts.
