Start with the job in front of you
Every public tool has a distinct purpose, visible limitations and related next steps.
Formula Health Checker
Inspect a pasted formula or the first worksheet in an XLSX file for broken references, fragile lookups and performance risks.
Open tool →Compare Two Lists
Find values that appear in both lists, only in the first list or only in the second list after safe normalization.
Open tool →Remove Duplicates from a List
Remove repeated lines while preserving the first occurrence and the original readable capitalization of each unique value.
Open tool →Merge and Combine CSV Files
Append two CSV, TSV or XLSX datasets and align their fields by header name in a downloadable CSV export.
Open tool →Compare Two CSV or XLSX Files
Compare two spreadsheet files using a selected key and group records into matched, missing, duplicate and conflicting buckets.
Open tool →Use explainable rules
Formula generation, schema suggestions and quick comparisons use visible deterministic logic rather than unexplained black-box decisions.
Keep business signals clear
Matched is green, duplicates and partials are amber, while missing or conflicting records are red. Brand indigo never competes with result semantics.
