🔒 Your file is processed entirely in your browser — it never leaves your device.
For NetCDF4/HDF5 files, use the HDF5 viewer.
Convert NetCDF to CSV — free and private
Drop a .nc file, pick a variable, slice the time or level you need, and download it as CSV (lat, lon, value). No Python, no xarray, no upload — the conversion runs entirely in your browser.
Why convert NetCDF to CSV here
The fastest path from a climate or ocean model file to a spreadsheet.
No Python required
Skip netCDF4, xarray and ncdump. No conda environment, no compiler — just drop the file and download CSV.
Stays on your machine
The file is decoded locally and never uploaded, so confidential or unpublished model output is safe.
Slice multi-dim variables
Pick a variable, then pin the time / level / ensemble dimensions to export exactly the 2-D field you need.
Ready for Excel & pandas
Plain lat,lon,value CSV opens directly in Excel, Google Sheets, pandas or R — no extra tooling.
