Extend the generator to formats (generate-formats.sql + format_generators in the port, same mechanism as engines). Convert the 65 format pages whose structured docs reproduce the page (content-neutral / whitespace-only). Deferred (kept hand-written): pages that include shared Mintlify snippets (<PrettyFormatSettings/>, <RowBinaryFormatSettings/>, <DataTypeMapping/> from /snippets/) which the Docusaurus->Mintlify transform can't synthesize, and a few (Values, HiveText, Arrow, ArrowStream, Parquet) whose structured description is less complete than the page and needs enriching.

## Description {#description}
|
|
|
|
The `JSONCompactStrings` format differs from [JSONStrings](/reference/formats/JSON/JSONStrings) only in that data rows are output as arrays, not as objects.
|
|
|
|
## Example usage {#example-usage}
|
|
|
|
### Reading data {#reading-data}
|
|
|
|
Read data using the `JSONCompactStrings` format:
|
|
|
|
```sql
|
|
SELECT *
|
|
FROM football
|
|
FORMAT JSONCompactStrings
|
|
```
|
|
|
|
The output will be in JSON format:
|
|
|
|
```json
|
|

|
|
"meta":
|
|
