DataLensia
Interact, explore, and visualize your data in the browser
Datalensia lets you load CSV, JSON, and NDJSON files to explore, filter, transform, and visualize structured data directly in the browser. Create complex data pipelines, generate flowcharts and Mermaid diagrams, validate JSON with detailed error reporting, take Markdown notes, and organize projects with folders — all within a single workspace. Everything runs locally on your device, ensuring your data stays private and secure.
Datalensia is built for developers, data analysts, data scientists, QA engineers, product managers, and researchers who need a fast, reliable, and privacy-first way to work with structured data.
We built Datalensia because existing data tools are often fragmented, overly complex, or dependent on cloud services. Our goal was to create a lightweight local-first workspace that combines data exploration, transformation, visualization, and documentation in one seamless experience without compromising privacy.
