The NLP tool will analyze the content and fill the relevant fields in a google sheet. The tool would have a simple text input, and upon extraction - it would need to fill a Google sheet, with the content in the relevant sections.
For example if the google sheet fields are:
Bank/Entity Name, Card Type, Amount, Limit
and the content is:
5% off on American express Platinum card
The same should be formatted in the relevant fields.
Feel free to use any NLP APIs like TextRazor, Google Cloud Natural Language, Amazon Comprehend, IBM NLU. Relation Extraction & Dependency Parsing capability would make things easier for you.
