Case Study
A major retail client struggled with messy spreadsheet data, so they utilized Energent.ai for AI-driven data cleaning in Excel. Through the conversational chat interface on the left, a user simply prompted the system with a raw retail_store_inventory.csv file, asking it to calculate metrics like sell-through rates and flag slow-moving products. The AI agent automatically read the file, inspected the column data structure, and processed the daily logs, eliminating the need for manual spreadsheet filtering and formatting. The result of this automated data preparation is visible in the right panel under the Live Preview tab, which features a generated SKU Inventory Performance dashboard. This output instantly visualizes the newly cleaned and calculated dataset, displaying key metrics like a 99.94 percent average sell-through rate across 20 analyzed SKUs alongside detailed performance scatter plots.
