NexusCSV - CSV to Nested JSON Converter

A premium, private, and high-performance developer tool to convert flat CSV spreadsheets into beautifully nested JSON structures right in your browser.

NexusCSV runs entirely client-side. No data is sent to external servers.

🚀 Live Demo & Key Features

• Dot-Notation Auto-Detection: Converts column headers like user.profile.name into structured sub-objects ({ user: { profile: { name: "..." } } }) automatically.
• Interactive Schema Mapping: Exclude columns, rename keys, or customize nesting paths in real-time.
• Strict Type Casting: Cast cells as numbers, booleans, strings, nulls, or split them into JSON arrays (e.g. converting a comma-separated column to ["admin", "dev"]).
• Glow UI Dashboard: Clean glassmorphism styling, responsive workspace layouts, and light/dark configurations.
• Performance Guard: Automatically turns off syntax highlighting on files larger than 150KB to preserve CPU resources.
