Excel Support Is Here — Upload .xlsx, Query with SQL, Export Instantly
By ParquetReader Team

Excel Is Still the World’s Most Common “Database”
A huge amount of real business data still starts life in Excel.
Budgets, extracts, CRM exports, finance reports, operational lists — all living in .xlsx files.
Until now, working with Excel often meant manual cleanup, copy/paste chaos, and slow tools when files got big.
That’s why this release matters: ParquetReader now supports Excel uploads — with the same fast exploration experience you already know.
Upload Excel, Explore Immediately
You can now upload .xlsx files directly into ParquetReader.
As soon as your file is loaded, you can:
- Search through your data
- Sort columns instantly
- Paginate through large sheets without freezing your browser
- Inspect schemas and values quickly
It feels like Excel — but built for speed, scale, and analysis.
SQL Queries on Excel Data (Yes, Really)
This is the big one: you can write SQL queries directly on your Excel data.
That means you can filter, group, aggregate, join, and validate your dataset without first converting it elsewhere.
Examples of things that become trivial:
- Find duplicates by key
- Validate totals and sums
- Build quick rollups (group by week/month/category)
- Spot outliers and missing values
Excel becomes queryable data — instantly.
Export Excel to Parquet, CSV, or JSON
Once you’ve explored (or queried) your Excel dataset, you can export it in the format you actually need:
- Parquet for analytics workflows and fast downstream processing
- CSV for compatibility and sharing
- JSON for APIs and dev tooling
You can even export the result of your SQL query, not just the raw sheet — which makes ParquetReader a clean bridge between messy spreadsheets and production data pipelines.
Why This Is a Big Step for ParquetReader
ParquetReader started as the fastest way to inspect and work with columnar data files.
Adding Excel support is a meaningful expansion of that promise: meet people where their data is — and upgrade it into something scalable.
For a lot of users, this removes an entire set of steps:
- No more “convert to CSV first”
- No more local scripts just to peek at the file
- No more slow spreadsheet tooling when files get heavy
Just upload → explore → query → export.
