FAQ
Frequently asked questions
Everything you need to know about parquet to excel converter.
How large files can I convert?
Conversion runs in your browser memory, so files with a few million rows convert in seconds; very large files depend on your device's available RAM.
Which sheet is used?
The whole table goes into a single sheet named Parquet, with the Parquet schema as the header row and one row per record.
Are dates readable in Excel?
Date values are exported as ISO 8601 strings, so they display consistently in Excel and Google Sheets without timezone confusion.
Can I edit the result and convert back?
Yes. Edit the workbook and use the Excel to Parquet tool to write the changes back to compressed columnar format.
Is my file uploaded?
No. The file is decoded locally via WebAssembly; neither the Parquet input nor the Excel output ever touches a server.
