JSON to Extraction Query

GUI that translates manual user selections on an imported JSON file into extraction query. Extraction query is a hybrid of JSON Path syntax and can be utilized by further services to create a table of extracted values. The component becomes useful once it is required to extract data subset of the particular JSON and define relations within the extraction.

Extraction query

The extraction query is a result of running the program. You can pass your own onFinish function that accepts a single value of OutputQuery type (details below).

Schema

The output of running the program is an object (dictionary) of the following type:

type OutputQuery = {
    path: string;
    columnNames: string[];
    columnPaths: string[]
}

Semantics

  • path stands for the JSONPath expression that is executed to extract the data from the initial JSON. Learn more.
  • columnNames is a list of columns' names. The size of that list is the same as the length of columnPaths. Learn more.
  • columnPaths is a list of columns' JSONPath-like paths.
