I keep an Excel sheet that lists up to 100 company names at a time together with their country of operation. I need a straightforward way to upload that file, have the names automatically enriched, and then receive three specific data points for every record: • primary email address • main phone number • full physical (head-office) address Whether the solution is a small web app, a command-line script, or an API workflow is secondary—the key is that I can drop an .xlsx file in, wait a short while, and download the completed sheet in the same structure with the new columns appended. Accuracy matters more than speed, so feel free to combine multiple data sources (e.g., Clearbit, Hunter, Google Places, LinkedIn scraping, or other public or paid APIs) as long as the results are reliable and clearly flagged when no match is found. Please include: • the working code or hosted interface, ready to accept up to 100 rows per batch (with clean error handling) • concise setup or deployment notes • one demonstration run on a sample file showing successful retrieval of email, phone, and address fields I am open to future scaling, but this first milestone is limited to the smaller batch size and the three contact fields listed above.
