Import autofill data from a file into Chrome

I have a CSV file of users (with email and name). Google Chrome stores its autofill data and you can add them manually here: chrome://settings/addresses

Is it possible to import the data automatically from the file?

Solution

  • The settings UI uses an internal API chrome.autofillPrivate.saveAddress (source).

    1. go to chrome://settings/addresses
    2. open devtools console
    3. paste and run the code below that adds an input button in the top right corner where you can select your CSV file: enter image description here
    for (const el of document.querySelectorAll('body > input'))
  el.remove();
Object.assign(document.body.appendChild(document.createElement('input')), {
  type: 'file',
  style: 'position:absolute; top:2ex; right:0; z-index:999',
  onchange(e) {
    if (!this.files[0])
      return;
    const fr = new FileReader();
    fr.readAsText(this.files[0], 'UTF-8');
    fr.onload = () => {

      for (const line of fr.result.split(/\r?\n/)) {
        const [name, email] = line.split(',');
        chrome.autofillPrivate.saveAddress({
          emailAddresses: [email],
          fullNames: [name],
        });
      }

    };
    fr.onerror = console.error;
  },
});
