What Parquet files are supported?

Tabular and record-oriented Parquet files up to 40 MB. Nested record groups are flattened row by row; the CSV keeps column names from the Parquet schema.

Does this keep all Parquet metadata?

No. You get the data as CSV. Parquet schemas, compression stats, and other metadata are not copied into the CSV.

What about special characters in the data?

Values containing commas or quotes are quoted so the CSV stays valid in any spreadsheet or parser.

How to convert Parquet to CSV

Upload a Parquet file up to 40 MB.
Press Convert file and download the CSV.

What you get

A single CSV file with a header row taken from the Parquet column names, then one row per record. Text values that contain commas or quotes are quoted so the file opens cleanly in Excel, Numbers, Google Sheets, or any text editor.
