Často kladené otázky

Základní odpovědi na technické otázky hodnocení a indexace.

How does the Excel formula explainer work?

You paste a formula; the tool parses functions and arguments using rule-based, open-source logic and explains what each part does—no paid AI API.

Is my spreadsheet data uploaded?

You only paste the formula text. The explainer does not need your full workbook unless you choose to share cell context in the UI.

Can it explain nested formulas?

Yes. Nested functions are broken into steps so you can see inner results feeding outer functions.

Does the explainer use paid APIs?

No. It runs free in the browser with open-source explanation logic and no paid LLM or spreadsheet APIs.

Will it tell me the exact cell result?

It explains expected behavior and argument roles. Exact numeric results still depend on the values in your sheet.

Who should use an Excel formula explainer?

Anyone inheriting complex workbooks—students, analysts, and managers who need to verify what a formula actually computes.
