## 12.11 Data Import and Export

This section describes routines for importing and exporting data into and out of Data Explorer. This includes support for Data Explorer (`.dx`) files, as well as industry-standard netCDF files.

### Data Explorer Format Files

Files in the Data Explorer format (see Chapter 3. "Understanding the Data Model" in IBM Visualization Data Explorer User's Guide) can be imported by the `DXImportDX()` routine and exported by the `DXExportDX()` routine.

`Object DXImportDX()` | Imports data from a Data Explorer file. See DXImportDX.
`Object DXExportDX()` | Writes an Object to a specified file in a specified Data Explorer format. See DXExportDX.

### netCDF Data

Data Explorer can accept industry-standard netCDF files, which describe only a subset of the Data Explorer data model capabilities. For example, netCDF files are limited to regular data. This routine is provided for compatibility with other systems that use netCDF.

`Object DXImportNetCDF()` | Imports data from a netCDF file. See DXImportNetCDF.
