Compare Tool
Two files. One truth.
CompareTool finds every difference in seconds; mismatched values, missing records, duplicate IDs field by field, with the numbers to back it up. Drop in your files. Pick your ID column. Hit compare. That's it. No formulas. No VLOOKUP. Runs in your browser — your data never touches a server. Works offline too. Catches: value changes, missing or new records, duplicate IDs, column mismatches, numeric and date deltas. Doesn't: send your data anywhere, require a login, or cost anything.

Built this after watching analysts waste hours manually spot-checking two exports side by side. Sheet Compare runs entirely in your browser; no login, no server, your files never leave your machine. Drop in two spreadsheets, pick your ID column, hit compare. You get field-level diffs, numeric deltas, missing records, duplicate flags — in seconds. Works offline too. Download it once, use it forever. Would love feedback from anyone doing month-end reconciliations or data quality checks.
