Inspect local Parquet metadata and export selected records. Local Parquet files up to 20 MB; up to 25,000 selected rows and 200,000 cells. Uncompressed and Snappy supported; unsupported codecs produce an explicit error. Nested values export as JSON text. Inspect row groups, schema and codec metadata before exporting.

Prepare the input

Inspect local Parquet metadata and export selected records.

Paste the supported structured data or log text. The sample loads only when explicitly selected and can be undone.

Review the method

Local Parquet files up to 20 MB; up to 25,000 selected rows and 200,000 cells. Uncompressed and Snappy supported; unsupported codecs produce an explicit error. Nested values export as JSON text. Inspect row groups, schema and codec metadata before exporting.

Keep the useful output

Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.

CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
