Extensions → Apps Script

Delete anything already there.

Paste the script below.

Click Run inside Apps Script.

Google may ask for permission the first time.

The script

Copy and paste this exact script into Google Apps Script:

function FIND_DOMAINS() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var lastRow = sheet.getLastRow();

  for (var i = 2; i <= lastRow; i++) {
    var companyName = sheet.getRange(i, 1).getValue().toString().trim();
    var domainRange = sheet.getRange(i, 2);

    // Skip row if the company name is empty or domain column is already populated
    if (companyName === "" || domainRange.getValue() !== "") continue;

    // Clean up parenthetical variations like "Alphabet (Google)" to avoid query distortion
    var cleanName = companyName.replace(/\s*\(.*?\)\s*/g, "").trim();

    try {
      // Use the open, free Clearbit Autocomplete API instead of scraping raw search engines
      var url = "https://autocomplete.clearbit.com/v1/companies/suggest?query=" + encodeURIComponent(cleanName);
      var response = UrlFetchApp.fetch(url, {muteHttpExceptions: true});

      if (response.getResponseCode() === 200) {
        var data = JSON.parse(response.getContentText());

        // If the API locates a match, pull the clean domain string directly
        if (data && data.length > 0 && data[0].domain) {
          domainRange.setValue(data[0].domain);
        } else {
          domainRange.setValue("Not Found");
        }
      } else {
        domainRange.setValue("API Error " + response.getResponseCode());
      }

      // Short delay to avoid rate limit constraints
      Utilities.sleep(300);

    } catch(e) {
      domainRange.setValue("Fetch Exception");
    }
  }
}

How to use it

1. Add company names in column A
2. Keep column B empty
3. Run FIND_DOMAINS
4. The script will add domains in column B

The script skips rows where column B is already filled, so you can safely run it again without overwriting existing results.

Example

Important note

This is a free first-pass domain finder.

It is useful for cleaning lead lists, preparing outbound data, and quickly matching company names to websites.

It is not perfect.

Sometimes generic company names may return the wrong domain or no result.

For important campaigns, always verify the final domains before using them.

---

• Cold email lead lists
• Company enrichment
• Outbound prep
• CRM cleanup

---

Quick reminder

Clean input gives better output.

• HubSpot

• Salesforce

Avoid messy names like:

• HubSpot lead list 2026
• Stripe old prospect
• Notion USA contact
• Salesforce exported data
