Spreadsheet skills → SQL judgment
ChatGPT can draft a JOIN in seconds. Owning the result when the row count mysteriously doubles — that’s on you. We teach the bridge from Excel/Sheets habits to queries you can trust.
Built for people who already live in spreadsheets
• You’re fluent in Excel or Google Sheets and SQL is the next gate at work (congratulations / condolences)
• You’re busy — you want a clear path and labs, not forty tabs and a vague sense of doom
• You want judgment (joins, blanks, “is this result sane?”), not trivia night for database theoristsNot for: CS majors hunting internals, or anyone who only wants a certificate to frame and ignore.

FAQ
Q: Do I still need this if I use ChatGPT?
A: Yes — for verification, joins, and spreadsheet→SQL thinking. AI is fast at drafts; someone still has to notice when the draft is confidently wrong.Q: Excel or Google Sheets?
A: Both. We speak spreadsheet; labs are in SQL. The cells don’t care which logo was on the menu bar.Q: Is this for absolute beginners?
A: Best if you already filter, sort, and look up data in a sheet. Total SQL beginners are welcome. Total “what’s a spreadsheet?” is a different adventure.
