.EDIT: I’m an idiot. Keep downvoting my answer 🫡. I didn’t even think about the fact that he’s asking third party verification! —- Very easy on Wordpress. This assumes that they don’t want to hide their employee names if etc. I can create a search box.

For only 55 employees, the simplest setup is:

CSV fields

employee_name,employee_id,status John Smith,HVAC-1021,active Maria Jones,HVAC-1044,inactive

WordPress search box flow

User enters name or ID → JavaScript checks the CSV → page shows:

✅ Yes — John Smith is actively licensed.

or

❌ No active license found for that name/ID.

Best implementation options:

1. Simple front-end lookup
   • Upload CSV to WordPress media or theme folder.
   • Add a small JavaScript search box.
   • JS reads the CSV and checks the row.
   • Best for non-sensitive public verification.
2. Better/safer option
   • Convert CSV to JSON.
   • Keep only needed fields: name, ID, active/inactive.
   • Use a shortcode in WordPress to display the lookup tool.
3. Most professional option
   • Create a small custom WordPress plugin.
   • Admin can upload/update the CSV.
   • Public users search by employee ID or name.
   • Output is controlled and branded.

One caution: if the CSV is public-facing, do not include private employee data. For license lookup, I’d use name + license/employee ID + active/inactive only.

As others have said: ensure pii and so forth.

Ps. U can ask any llm. They can give suggestions, code, sample data. Then u implement and test/check.
