Case Study
To demonstrate the power of concatenating datasets with AI, Energent.ai was tasked with merging two separate spreadsheets of event leads into a unified system. Through the platform's left-hand chat interface, a user provided a target URL and prompted the agent to download the data, concatenate the files, and execute a fuzzy-match by name, email, and organization to remove duplicates. The AI seamlessly translated this request into action, visible in the workflow steps where it autonomously deployed fetch and bash curl commands to secure the target CSV files. The concatenated data was then made available as a merged leads document and transformed into an interactive dashboard within the Live Preview window, titled Leads Deduplication and Merge Results. This final interface provided a clear breakdown of the data concatenation process, highlighting the exact number of duplicates removed via a Fuzzy Match badge alongside rich visual charts categorizing Lead Sources and Deal Stages.
