0 bytes uploaded. Logic Hider (Formula → Value) runs entirely in your browser using SheetJS and ExcelJS. Your spreadsheets never leave your device.
Excel caches the last calculated result in the file. ExcelJS reads that cached value. If the cache is empty (force-recalc workbook), the cell will show 0 or blank.
Standard cell formulas, array formulas, and XLOOKUP/dynamic array spill results are all converted. Named ranges and data validation rules are preserved.
