My Parquet has more rows than Excel allows. What then?

Excel's limit is 1,048,576 rows per sheet. Split the output across sheets or files in the same run, or filter down first in the Explorer.

Can it read a partitioned directory?

Yes — point it at the folder and the parts are read as one table, which is how most warehouse exports arrive.

Will dates come across properly?

Yes. Parquet records the type, so dates arrive as dates rather than as text or as a serial number.

Parquet to Excel Converter

The most direct route from a data team's export to something the rest of the business can read. DataTray opens the Parquet — file or partitioned directory — and writes a workbook, with the types Parquet already records carried straight across.

Drop in your files — Workbooks land in DataTray's output folder. Nothing about the Parquet is modified.

Why convert

Types come across intact

Parquet stores the type of every column, which means a conversion into Excel does not have to guess. Dates arrive as dates, integers as integers, and the long identifier that would have become scientific notation via CSV stays as it was written.

Handing warehouse output to someone who works in Excel.
Turning a partitioned export directory into one workbook.
Reviewing a Parquet file's contents without a notebook or a SQL client.
Getting a dataset into a form you can pivot and chart.

How it works

Convert Parquet to Excel in a few clicks

1
Open the Parquet
A file or a directory of parts, read as one table.
2
Trim it if you need to
Excel stops at 1,048,576 rows per sheet, so filter or split first if the dataset is larger.
3
Write the workbook
Types come from the Parquet schema rather than being re-inferred.
