?Frequently Asked Questions
Are Excel formulas converted?
Formulas are evaluated and converted to their calculated values. For example, if cell A1 contains '=SUM(B1:B10)', the Parquet file will contain the numeric result, not the formula itself.
Can it handle multiple sheets?
Currently, the converter processes the first sheet only. If you have multi-sheet workbooks, convert each sheet separately by saving them as individual Excel files first.
What about Excel formatting and colors?
Parquet is a data format, not a presentation format, so visual formatting (colors, fonts, borders) is not preserved. Only the raw data values are converted.
