Invoice to Sheet is simpler to use
Docparser and Mailparser extract data from a variety of document types and emails into a variety of formats. They are good products but are sophisticated.
Invoice to Sheet does one thing and it does it well: extract structured data from your Gmail invoice attachments to a Google Sheet.
All providers use a different invoice template and sometimes they change it. Every invoice you receive can have a different structure and design than the last. You shouldn’t have to configure your extraction tool every time you get a different invoice design. Invoice to Sheet was built with an AI that can extract structured data automatically no matter what the invoice looks like, without any configuration.
In comparison, Docparser and Mailparser require you to manually set rules every time it encounters a new-looking document or email. It’s easy to use if all your documents and emails are structured exactly the same. However, it requires a lot of initial configuration and maintenance work in many instances.
