What's the most time-consuming part of your data analysis workflow?

I've been working on tools to make data analysis workflows easier, and I'm curious about how other data analysts approach their day-to-day work.

What's the part of your workflow that takes up most of your time?

1. Cleaning messy datasets

2. Validating data quality

3. Writing and optimising SQL queries

4. Feature engineering

5. Building dashboards and reports

Do you handle these manually, use existing tools, or have your own automated workflows?

Would love to hear what works for you and what still feels unnecessarily complicated.
