I have an excel spreadsheet file downloaded to file manager with about 50000 zip code records.

I am trying to add/build a dropdown select list of usa zip codes to ecommerce addon for probably under advanced settings.

i was first thinking of using customer choice with Select.Parameter however I would need to input about 50,000 records, I am 62 yo, think maybe I would pass away before completion/

Then I thought maybe a product attribute, but again same worry on my age. Did I mention I do collect some pensions already.

is there any addon to the ecommerce addon for zip codes or something i could use with ecommerce as part of my customer ordering and checkout process.

out of ideas

thx
