All of the values in the JSON column will be transformed to a JSON array with "JSON key" key complemented by the custom key/value pairs, or just the array if the option Omit root is selected. (The JSON content in the file can be pretty-printed.) 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 by the Custom key/value pairs and the Collect into array options.

Options

JSON column

The JSON column providing the values for the root key.

Output file

Location to save the file (can also be a remote URL).

Overwrite existing file

When checked, existing files might be overwritten.

Pretty print

When checked, each level of the JSON value will be indented, multiple lines are created, else a dense format is written.

Omit root

When selected, only the object or the array is returned (custom key/value pairs are not applicable).

Add root object with key

Key to the JSON values object or array in the root object.

Custom key/value pairs

Additional key/value pairs to the root object (not applicable when no root should be created).

Collect into array

The rows are collected to a JSON array.

Collect into object with key

The rows become an object within another object with the keys specified by the selected column's values (will fail if there are duplicates).
