JSON Row Combiner


Combines JSON values in a column to a single JSON value (with an array for the JSON values from the column). The output looks like this:

  "JSON key": [
    {"json":"from Row1"},
    {"json":"from Row2"}
  "custom key":"custom value"
where the JSON key can be specified with the Add root object with key parameter, the "custom key":"custom value" is specified with the Custom key/value pairs and the Collect into array options.
All columns and rows will be removed or collapsed to a single cell.
