Data tool for Excel

This tool functions as a data calculation and transformation engine for Excel. It accepts input data ranges and per-row transformation rules, then produces derived metrics in a target column or sheet. It is designed for experienced Excel users who need repeatable, rule-based data processing without exporting data to external tools. The tool reduces manual formula assembly and keeps calculations within the workbook workflow.\n\nConceptually, each row is processed according to defined rules and data types. Supported operations include arithmetic combinations, conditional mappings, normalization, rounding, and date or text transformations. Validation enforces numeric ranges, date formats, and required fields, returning clear error flags for problematic rows.\n\nAudience and value: finance, operations, marketing, and data teams who perform routine data wrangling in Excel benefit from reduced task time, improved consistency, and easier audit trails. Unique differentiators include templates for common workloads, safe in-place or copy-on-write output, and seamless integration with existing workbooks. Core features include multi-field input, rule-based transformations, type handling, template sharing, and robust error handling. Typical use cases include column scaling, currency normalization, date standardization, and scenario-based metric calculations.
