Adding processors to a dataset

Processors are tools that can be used in order to modify, improve, or enrich the data of a dataset. In the Opendatasoft platform, processors are classified into 4 different categories:

  • Processors for geographical mapping

  • Processors for dates handling

  • Processors for text transformations

  • Processors for generic operations

To add a processor to a dataset:

  1. In the Processing tab, click on the Add a processor button.

  2. Choose the processor to add to the dataset.

  3. Using the documentation of the chosen processor, fill in the right parameters to set the processor.

  4. (optional) Click on the edition icon icon-edit to rename the processor. This step can especially be useful when a lot of processors are applied to a dataset, including multiple processors of the same type (for example, renaming the multiple Expression processors applied to a dataset to know more easily which one contains which expression).


You may need to click outside the processor box once the parameters are configured to make sure the processor and the changes it triggers are taken into account and applied to the dataset.


No matter the processor, always use the technical identifiers of the fields to process, never the labels.

Geographical processors

Geographical processors are divided into 4 categories, according to what is tried to being achieved:

  • Geocoders: to convert a human-readable address into a geo point.

  • GeoJoin processor: to retrieve geoshapes from normalized codes for country-specific administrative divisions. The GeoJoin processor supports several countries, each of which features several indexing codes like postcode, state or region identifier, etc.

  • Retrieve Administrative Divisions processor: to retrieve the name, code, and geoshape of country-specific administrative divisions enclosing a geopoint.

  • Converters & Functions: to simplify, convert or normalize geographical data, or run computations based on them.
