HTML Form Entry AutoComplete from CSV List

We are building a form which requires a user to select a health facility (one out of 1,500) via an auto-complete search from data stored in a CSV file (no need to have a database table for it) and save the value in a Text Obs value, then have the same list displayed during editing

The text file has only two columns see sample below

uuid name
ab4uj76 Health Facility 1
dimnyu7 My Family Clinic
pl098jb Main Regional Referral Hospital

A couple of questions

  1. How would one support this in HTML Form Entry - we already have the text obs concept setup
  2. How can I load the CSV into memory and use it as an autocomplete

Looking forward to hearing from you all cc @mogoodrich @mksd @mseaton
