I spent a week on regex before realizing AI agent was the answer for data extraction
The author shares their experience of trying to extract structured data from free-form emails using various methods. Initially relying on regex and NLP tools like spaCy, they faced numerous challenges due to the unstructured nature of the data. Ultimately, they found success by utilizing an AI agent that could follow instructions and output structured data in JSON format.
