Users can easily upload two CSV or Excel files, which serve as the primary inputs for the matching process. Once uploaded, the engine analyzes the data to identify a specific column that will be used as the reference point for matching entries across the two datasets. The fuzzy matching algorithm adeptly assesses the similarities between entries in the chosen column, accommodating variations in formatting, spelling, and other inconsistencies. This feature proves particularly beneficial in cases where data may be inconsistent or incorrectly formatted. Upon completing the analysis, the engine produces a new sheet that not only populates the missing column in the original dataset but also includes a confidence score for each match. This score reflects the engine's certainty regarding the accuracy of its matches, enabling users to evaluate the reliability of the results. By leveraging the two uploaded files, this fuzzy matching engine simplifies the data reconciliation process, resulting in a more robust and trustworthy dataset for future analysis and reporting.
