Why convert Parquet to CSV?
Convert Parquet to CSV for universal compatibility. CSV works in Excel, Google Sheets, text editors, and any tool. Perfect when you need to share data with non-technical users or use tools that don't support Parquet.
Will I lose data converting Parquet to CSV?
No! All data is preserved during conversion. However, CSV is plain text (no data types), so numeric precision might be formatted differently. The conversion is lossless for data values.
Can Excel open Parquet files?
No, Excel cannot open Parquet files directly. That's why you need to convert Parquet to CSV first. Then you can open the CSV in Excel, Google Sheets, or any spreadsheet tool.
How large will the CSV file be compared to Parquet?
CSV files are typically 5-10x larger than Parquet. A 2GB Parquet file might become a 10-20GB CSV. This is because Parquet uses advanced columnar compression while CSV is plain text with no compression.
Can I batch convert multiple Parquet files?
Yes! Select entire folders and convert hundreds of Parquet files to CSV in one operation. Much faster than online tools that limit file counts or require individual uploads.
What encoding should I use?
UTF-8 is recommended for universal compatibility and international character support. Use ASCII only if you're certain your data contains only English characters. UTF-8 preserves all special characters, emojis, and international text.
Is Parquet to CSV conversion free?
Completely free with unlimited conversions. No file size limits, no watermarks, no credit card required.
Should I keep the Parquet file after converting?
Yes! Keep the Parquet file for your own analysis (10-100x faster queries). Export to CSV only when sharing with others or using tools that require CSV.
