I spent a week using regex to extract data. It failed.
I needed names, dates, and amounts from emails. Emails are messy. People write how they talk.
Regex is too stiff. One small change breaks the pattern. I tried spaCy. It missed relative dates like next Tuesday. I tried BERT. Training took too long.
Then I used an AI agent. I gave it a schema and a prompt. It returned clean JSON.
Benefits:
- Change the schema in seconds.
- It understands context.
- It is easy to maintain.
Trade-offs:
- Costs money per token.
- Slower than local code.
- Risk of hallucinations.
My advice: Use regex for simple patterns. Use AI for fuzzy text.
