Function mappings and compatibility details will appear after translation.

    Structure and reverse-translation checks do not calculate formulas or validate argument counts. Test the result in Excel. Understand these checks →

    02 / FUNCTION DICTIONARY

    500 functions.
    One language index.

    Search canonical English identifiers or localized names, check version compatibility, and save the functions you use most. Favorites stay in this browser.

    03 / HOW IT WORKS

    More than find and replace.
    It understands formula boundaries.

    01

    { }

    Scan formula structure

    Identify function calls, strings, array constants, structured references, workbook references, and bracket depth.

    02

    A↔Ä

    Map canonical functions

    Resolve each function to its canonical English identifier, then find its localized target name.

    Validate before delivery

    Check quotation marks and all three bracket types, then reverse-translate and flag unrecognized functions.

    04 / COVERAGE

    Start with the languages you use.
    Keep expanding the map.

    Formula Atlas currently connects 500 canonical function identifiers across 18 languages. Counts show registered name mappings, not Excel’s total function support. Identical names can be valid across languages. Missing mappings use English and are flagged; Japanese has only 60 registered entries. Data and verification scope →
