It can parse receipts from big online venders and will be able to parse purchases made with a credit card. However, I think you might be asking if it can parse credit card statements. I don't believe that it currently works on credit card statements, since we're focusing on new purchases now.
However, since there's not a ton of different credit cards, you should be able to write your own regex expressions and pull out the valuable data in those emails yourself.
Thanks, that is helpful. If I want to parse a receipt from a brick and mortar store like Walmart or Safeway or Albertson, since I do not receive receipt via email for them. I guess, I will have to scan receipt via a smartphone and then send via email to myself and then have context.io parse the attachment? Will that work?
