Open multi‑gigabyte CSV files instantly
CSView is a high‑performance, read‑only CSV viewer built for very large files.
It opens multi‑gigabyte CSVs quickly and remains responsive even with hundreds of millions of rows.
CSView prioritises fast startup, low memory usage, and smooth navigation, allowing you to inspect the beginning of a file immediately while the rest is indexed in the background - even for very wide CSVs with thousands of columns.
CSView comfortably handles CSV files larger than 4 GB, making it suitable for workloads where tools like Excel, Numbers, and traditional CSV editors struggle or fail.
Common use cases:
- Bioinformatics and scientific datasets
- Database exports
- Log files and machine‑generated data
CSView is read-only by design, and focuses on viewing, searching, and inspecting large CSV files quickly and safely, without modifying the source data.
Current features:
- Fast, table‑style CSV viewing
- Immediate access to the start of very large files
- Efficient background indexing for smooth scrolling and navigation
- Designed for multi‑gigabyte CSV files and very wide tables
- Consistent memory usage regardless of the size of the file being viewed
- Fully native Apple Silicon support
