Describe what you want a Notion database property to calculate and get a paste-ready formula, a step-by-step explanation and fixes for the type errors that usually trip people up.
Explain what the formula should do and list the property names and types involved, such as a Due date, a Status select or a Price number. Pick a length and send. The tool returns a formula you can paste into a formula property, explains every function it uses, shows an example result, and covers common errors like empty dates or mixing text with numbers, plus an optional upgrade idea.
Copy property names exactly, including capital letters and spaces, because Notion matches them precisely. Tell the tool each property type so it can convert values correctly. For long formulas, ask for a version using let to keep it readable. If Notion shows an error, paste the message back and ask for a fix. Test with a few rows that include empty values before rolling it out.
Does it use the newer Notion formula syntax?
Yes. Formulas are written for the current Notion formula language, including let, ifs, map and filter. If you are on an older setup, ask and it will explain the differences.
Why does my formula show a type error?
Usually a number, date or text value is being combined with a different type. Paste the formula and the error, and the tool will add the right conversion or empty check.
Can it make progress bars and status labels?
Yes. Ask for a progress bar from a checkbox or rollup, or a label that changes based on dates, and it will build the formula with an example output.
