Turn a Parquet file into a CSV you can open in Excel. It is converted in your browser, so the file never leaves your device.

Drop PARQUET files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the CSV, or download everything as one ZIP if you converted several files.
The PARQUET to CSV converter is part of this page and runs inside your browser. Your datasets are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
Parquet is a columnar format used by data lakes, Spark and analytics tools. Excel and most spreadsheets cannot open it, but they open CSV. The column names and values come across as text; Parquet's column types and its compression do not.
Column types are read from the file and nested columns stay nested. An encrypted Parquet file is refused, and so is one too large to hold in a browser tab (about 40 million cells).
Parquet stores a table column by column, with the type of every column recorded in the file and each column compressed on its own. That makes it small and quick to scan for analysis, which is why data lakes and warehouses use it. It cannot be read in a text editor or a spreadsheet.
Opens in pandas, Spark, DuckDB, BigQuery, Snowflake and other analytics tools; not Excel
PARQUET converterCSV is a table written as text: one row per line, values separated by commas. Every spreadsheet and database can import and export it, but it holds one sheet only and no formatting, formulas or data types.
Opens in Excel, Google Sheets, Numbers, databases and any text editor

No. The PARQUET to CSV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything CSV has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the PARQUET file, press Convert and save the CSV. There is nothing to install.
Yes. Binary data files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
