/**
 * The built-in **JSON exporter**.
 *
 * JSON needs no library, so — unlike Excel and PDF — it is implemented directly
 * in the core and is always available, with no registration step.
 *
 * It emits an array of objects, one per exported row, keyed by each column's
 * `field` (or its header, with {@link JsonExportOptions.useHeadersAsKeys}).
 * Values are the grid's **logical** values, not its display strings: a number
 * stays `1200`, a boolean stays `true`, and a missing value is `null` rather
 * than absent — so a round-trip through `JSON.parse` gives back data, not text.
 * Hosts that want the on-screen strings ask for
 * {@link JsonExportOptions.useFormattedValues}.
 *
