Enrich data using regular expressions


Install this plugin in the same environment as Datasette.

datasette install datasette-enrichments-re2


This enrichment allows you to run a regular expression against a column and perform one of the following:

  • Execute a search and replace against that column
  • Extract the first matching result and store that in the specified column (adding a column if necessary)
  • Extract all matching results and store them as a JSON array in the specified column. If the regular expression uses named capture groups this will be an array of objects, otherwise it will be an array of strings.
  • Execute a regular expression with named capture groups and store the results in multiple columns, one for each of those named groups


To set up this plugin locally, first checkout the code. Then create a new virtual environment:

cd datasette-enrichments-re2
python3 -m venv venv
source venv/bin/activate

Now install the dependencies and test dependencies:

pip install -e '.[test]'
