Somebody exported the spreadsheet. The formulas are gone, but the numbers still remember them.
Drop in a CSV or Excel file of plain values. Unbake works out the formulas that most likely produced each column: exact coefficients, lookups, tax tables and running totals. Then it flags the cells that break them and suggests the most likely slip, such as swapped digits or a slipped decimal point. Suggestions are inferences from the data, not proof, so always check them against the source.
HypothesiseFor every numeric column, Unbake builds a library of candidate terms: other columns, their products and ratios, the column's own previous row, and lookup tables keyed by text columns.
Survive the typosRANSAC fits each combination from tiny random row subsets, so a few wrong cells can't bend the answer. Coefficients snap to the simplest number that loses no rows: 0.0825, 1.5, 1/3.
BlameWhere rows break a formula, a solver asks which single cell, if corrected, repairs the most breaks without breaking anything else, and whether the fix looks like a human slip.
