I've already read a Q&A stating that because NetCDF does not support primitive string type variables, that it is impossible to export a string to a NetCDF file.

For example:

testvalsnodvar = {"VOL_FRACTION01"}; Export["W:\\LPF_extractor\\test.nc", {"vals_nod_var" ->testvalsnodvar}, "Datasets"]

gives a Java error stating that this is an incorrect format for Datasets. Is there a way around this or am I stuck?


Convert the string to a list of integers using ToCharacterCode, and then convert back using FromCharacterCode.

testvalsnodvar = {"VOL_FRACTION01"};
Export["test.nc", {"vals_nod_var" -> 
   ToCharacterCode@testvalsnodvar}, "NetCDF"]
(* "test.nc" *)

  "test.nc", {"Datasets", "vals_nod_var"}] // FromCharacterCode
(* {"VOL_FRACTION01"} *)
  • $\begingroup$ That works great for working strictly in Mathematica, however, reading this into another program does not work so well. I suppose there is no way around it if my only option is to convert strings into ASCII code. $\endgroup$ – plasmacaster Apr 30 '16 at 0:33
  • $\begingroup$ From what this page says strings are not a natively supported data type. $\endgroup$ – Jason B. Apr 30 '16 at 6:09
