File to qr code and qr code to v card pdf make google apps script code

Here's a breakdown of the functionalities you requested and Google Apps Script code for each:

1. File to QR Code:

Unfortunately, Google Apps Script cannot directly access and convert file content into QR codes. This functionality requires additional libraries or services not natively supported.

2. QR Code to vCard:

This is achievable using external libraries like the ZXing library. However, Google Apps Script doesn't allow external libraries due to security restrictions.

Alternative Solutions:

• File to QR Code (External Tool):

  • Upload the file to a free online QR code generator like https://www.qrstuff.com/.
  • Use the generated QR code for your purpose.

• vCard Creation (Manual or Spreadsheet):

  • Create a vCard file manually with a text editor.
  • Use a Google Sheet with formulas to build vCard data and generate the vCard text content.

3. QR Code Generation within Google Apps Script:

This is possible! Google Charts API allows generating QR codes from text data. Here's the code:

JavaScript

function generateQRCode(text) {
  // Replace 150 with desired QR code size
  const qrCodeUrl = `https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=${encodeURIComponent(text)}`;
  const blob = UrlFetchApp.fetch(qrCodeUrl).getBlob().setName("qr_code.png");
  return blob;
}

4. PDF Creation:

Google Apps Script provides functionalities to create PDFs using the DocumentApp service. You can integrate the generated QR code image into a document and then convert it to PDF.

Here's an example combining QR code generation and PDF creation (replace "Hello World" with your actual vCard data):

JavaScript

function createVCardPDF() {
  const vCardText = "BEGIN:VCARD\nFN: John Doe\nTEL:+1234567890\nEMAIL:johndoe@example.com\nEND:VCARD";
  const qrCodeBlob = generateQRCode(vCardText);
  
  const doc = DocumentApp.create("vCard");
  const body = doc.getBody();
  const image = body.appendInlineImage(qrCodeBlob).setWidth(100).setHeight(100);
  body.appendParagraph("This is a vCard").setAlignment(DocumentApp.HorizontalAlignment.CENTER);
  
  const pdfBlob = doc.getAs("application/pdf");
  pdfBlob.setName("vCard.pdf");
  DriveApp.createFile(pdfBlob);
  
  // Close the temporary document
  doc.close();
}

Remember:

• Replace "Hello World" with your actual vCard data.
• This script creates a temporary document and then converts it to PDF.

This approach provides a more integrated solution within Google Apps Script, but creating vCards directly is not supported.
