Google Sheets QUERY builder
Pick your columns and conditions; get the formula. QUERY's syntax is unmemorable rather than hard — the clause order is fixed, the column references change depending on where your data came from, and every value type quotes differently. This gets all three right.
Fill in the range and hit Build.
You'll get a formula like this, plus a plain-English reading of it and a warning for each thing that usually goes wrong:
=QUERY(A1:E200,
"select A, B, D where D > 1000", 1)
Nothing is sent anywhere — the formula is composed in your browser.
