  1. Retrieve all values using getValues , and the values are searched from the retrieved array.
  2. Use TextFinder.
  3. Use Query language.

TextFinder is part of the Spreadsheet Service and provides methods for finding or replacing text within a range, sheet or spreadsheet. There have been some reports on Stack Overflow that the TextFinder methods can be relatively slow to execute compared to using native JavaScript techniques.

This is a nice example of how you can easily drop in existing JavaScript libraries into your Apps Script project by using a HTML dialog. The post also has some nice tricks for handing image data, in particular, from getDataFromQRCode() the image data is passed into the HtmlService :

const html = HtmlService.createTemplateFromFile("index");
html.image = JSON.stringify(blob.getBytes()); // adding image data
SlidesApp.getUi().showModalDialog(html.evaluate(), "sample");

This is added in client side with a printing scriptlet:

image.src = `data:image/png;base64,${btoa(String.fromCharCode(...new Uint8Array(Int8Array.of(...JSON.parse(<?= image ?>)).buffer)))}`; 

Another way you could achieve this is base64 encoding the image server side with Utilities.base64Encode() .
