About the project

About CellLingo.online

CellLingo is an independent spreadsheet utility and learning site built around a simple idea: formula problems are easier to solve when syntax, references, locale differences and workbook logic are treated as separate questions.

What CellLingo does

The site provides focused browser-based tools for checking formula structure, repairing safe copy-and-paste issues, formatting nested formulas, translating explicitly mapped function names, converting references and exploring spreadsheet functions and errors.

Browser-firstCore formula tools in this version run locally in your browser rather than requiring a workbook upload.

Transparent limitsCellLingo does not claim to evaluate your workbook data, named ranges, external links or business rules.

Explicit reference dataLocalized function names are published only where the mapping exists in the project dataset.

How guides are maintained

Function guides combine reference syntax with original examples, debugging notes and common mistakes. Articles display their WordPress author and update date. When a mapping or example needs correction, readers can use the Contact page to report it.
