Hi there,
I can give you desired results within 2 hours
I'll send you link which will allow you to select file to import numbers, lookup those numbers on given api, produce result set, display it on page and allow you to download csv of results.
- link I will send you will be from my demo severs
- I'll give you the script I'll create in php so you can host it anywhere you want
- You will be able to use script when ever you need
Alternate solution is I will give an excel file with macro that will allow you to import numbers from file and lookup those numbers on your api and update the excel file for each number with result. Either solution you want I will deliver.
Ping me to let me know if this fulfill your needs and get started
Regards,
Ahmed
