 A better approach is to create separate columns for individual fields, referred to as shredding or subcolumnarization.
 [VariantShredding.md](VariantShredding.md) describes the Variant shredding specification in Parquet.
 
-## Conversion to JSON
-
-Values stored in the Variant encoding are a superset of JSON values.
-For example, a Variant value can be a date that has no equivalent type in JSON.
-To maximize compatibility with readers that can process JSON but not Variant, the following conversions should be used when producing JSON from a Variant:
-
-| Variant type     | JSON type | Representation requirements                              | Example                                  |

-| Boolean          | boolean   | `true` or `false`                                        | `true`                                   |

-Notes:
-
-* For timestamp and timestampntz, values must use microsecond precision and trailing 0s are required
-* For float and double, infinities and not a number values are encoded as strings: `"Infinity"`, `"-Infinity"`, and `"NaN"`
