Large language models are perfect for data extraction tasks as they can work across a range of document layouts without human intervention. The extracted data can then be sent to a variety of datastores such as spreadsheets, accounting systems and/or CRMs.

**Tip:** The \"Structured Output Parser\" ensures the AI output can be
inserted to our spreadsheet without additional clean up and/or formatting. "
