Convert NetCDF to CSV Online | Free, Secure & Fast Tool

About This Tool

This NetCDF to CSV Converter is a professional-grade web utility designed for scientists, researchers, and GIS specialists. Unlike other tools that require you to upload sensitive data to a remote server, this tool processes everything locally on your device using advanced JavaScript libraries.

NetCDF (Network Common Data Form) is widely used in climatology, meteorology, and oceanography. However, viewing this data in standard spreadsheet software like Excel or Google Sheets can be difficult. Our tool bridges this gap by allowing you to extract specific variables and convert them into a universally compatible CSV format.

How to Use

• Step 1: Drag and drop your .nc file into the upload zone, or click to select a file from your computer.
• Step 2: Wait a moment for the file to be parsed. The tool will automatically list all available variables found in the file.
• Step 3: Select the variable you wish to export from the dropdown menu. A preview of the data will appear instantly.
• Step 4: Click "Download CSV" to save the file, or "Copy to Clipboard" to paste it directly into Excel.

Features & Benefits

• 100% Client-Side: Your data never leaves your browser. Perfect for confidential or proprietary datasets.
• Selective Export: Don't waste time converting the whole file. Pick exactly the variable you need (e.g., "temperature", "precipitation").
• Multi-dimensional Support: Automatically flattens complex multi-dimensional arrays (Time, Lat, Lon) into a readable tabular format.
• Instant Preview: Verify your data before downloading with the built-in table viewer.
