About CSV and PARQUET
text/csv
CSV is a simple text-based format for storing tabular data using commas as delimiters. It is highly portable and supported by virtually all databases, spreadsheet tools, and programming languages. CSV does not support formatting or formulas but excels at data interchange and exports.
application/vnd.apache.parquet
Parquet is a column-oriented data storage format for Hadoop.
Conversion Notes
CSV and PARQUET use different internal structures, and our converter handles the mapping automatically. Text content, core data, and primary media streams are preserved. Format-specific features with no equivalent in the target — proprietary metadata, platform-specific extensions, or advanced layout instructions — are omitted from the output file.
