## What is Parquet Viewer & Converter?

Parquet Viewer is a Parquet reader and Parquet file viewer for iPhone, iPad and Mac. Open an Apache Parquet file and see every row and column in a clean table, check the schema and read the column statistics, all without writing a line of code. Made for data analysts, data engineers and anyone who receives a Parquet file and just needs to see what is inside.

EXPLORE EVERY FILE
• Open .parquet, .parq and .pq files from the Files app, iCloud Drive, Mail or AirDrop: a Parquet opener for every file you receive
• Browse rows and columns in a table, with the row count, column count and file size on top
• Tap a column to sort it, filter any column, and page through large files
• See the schema: every column name and type, and which columns can be empty
• Read the statistics of every column: null counts, distinct values, minimum and maximum, compression and encoding

CONVERT, QUERY AND ANALYZE
These tools require an in-app purchase:
• Parquet to CSV: convert a Parquet file to CSV for any spreadsheet, database or script
• Parquet to JSON for web and API work, and Parquet to Excel for a workbook you can open in Excel
• CSV to Parquet and JSON to Parquet: a built-in Parquet converter that turns CSV and JSON files into Parquet
• Write SQL queries against your Parquet data and read the results as a table
• Search every row of a file for any value
• See histograms, distributions and category breakdowns for your columns

Open a file from the Files app, Mail, AirDrop or any app's Share Sheet, or tap "Open File" inside Parquet Viewer. No account, no login required. Works on iPhone, iPad and Mac, in 12 languages. Every file stays on your device, nothing is uploaded.
