Downloading a dataset

Huwise datasets can be downloaded in various formats. Flat file formats are always available for any dataset. Other formats may be available, notably if the dataset contains geographical coordinates.

1. On a dataset, click on Export data on the right or the export data icon among the icons in the upper-right. Choose the file format to download.

2. Perform one of the following actions:

   • Click Whole dataset next to the desired format

     

   • If you have filtered the data and you want to export only the filtered data, instead click Only the selected records next to the desired format

     

When you download a dataset, by default the labels for the data will match those you see in the table view. If you prefer the download use the the technical labels (those visible in the dataset's schema), you can do so using the following steps.1) Right-click on Whole dataset for the designed format, copy the URL, and paste it into your browser 2) Find use_labels_for_header=true, replace "true" with "false", and hit enter You can also export datasets in other formats using the Huwise Search API.

A dataset can be downloaded in the following formats:

Flat file formats

• CSV (Uses a semicolon (;) as the separator)

• JSON

• Excel (.xlsx)

Geographic file formats

The geographical coordinates of a dataset are expressed in WGS84 by default. If provided by the data producer, additional geographical projections may be available in the drop-down menu displayed above the export formats.

Geographic exports cannot contain more than one geographical shape type (point, polygon, linestring, etc.). If the dataset contains one geoshape field with multiple shape types, only the first type of the first non-empty record will be kept in the export.If the dataset contains multiple geographical fields (geoshape or geo_point_2d), only the first shape type of the first non-empty record will be kept in the export.

• GeoJSON

• Shapefile
  Shapefile exports cannot contain more than 50,000 records. It is a limitation from the Shapefile specification itself.

• KML

• FlatGeobuf (FGB)

• GPX

Data analysis file formats

• Parquet (more information)
