    const imageUrl = data[i][0]; // Image URL in the first column

  }
}


function getTextFromImage(imageUrl) {
  const apiKey = 'K84588088688957';
  const apiUrl = `https://api.ocr.space/parse/imageurl?apikey=${apiKey}&url=${encodeURIComponent(imageUrl)}&language='tha'`; // Corrected: added backticks


  const options = {
    method: 'get',
    muteHttpExceptions: true
  };
 
  const response = UrlFetchApp.fetch(apiUrl, options);
  const json = JSON.parse(response.getContentText());
 
  // Extract the parsed text, or show "No text found" if none
  const extractedText = json.ParsedResults && json.ParsedResults[0]
                          ? json.ParsedResults[0].ParsedText
                          : "No text found";

This is a great OCR video tutorial, thanks for posting it. Support for Thai OCR is only available in OCR Engine2. The default ocr engine is 1. Thus you need to specify the use of ocr engine2 in your call, then it should work fine:

So in the above please change

const apiUrl = https://api.ocr.space/parse/imageurl?apikey=${apiKey}&url=${encodeURIComponent(imageUrl)}&language='tha';

to

const apiUrl = https://api.ocr.space/parse/imageurl?apikey=${apiKey}&url=${encodeURIComponent(imageUrl)}&ocrengine=2&language='tha';`

:point_right: I simply added the &ocrengine=2 parameter. All else stays the same.
