Convert NetCDF to JSON — free and private
Drop a .nc file, pick a variable, slice the time or level you need, and download structured JSON. No Python, no xarray, no upload — the conversion runs entirely in your browser.
Why convert NetCDF to JSON here
Structured, code-ready output from climate and ocean model files.
No Python required
Skip netCDF4, xarray and ncdump. No conda environment, no compiler — just drop the file and download JSON.
Stays on your machine
The file is decoded locally and never uploaded, so confidential or unpublished model output is safe.
Structured for code
JSON with coordinates and values, ready for JavaScript, web maps, notebooks or any data pipeline.
Slice multi-dim variables
Pin the time / level / ensemble dimensions to export exactly the 2-D field you need.
