Online CSV Viewer & Data Grid — Sort, Filter & Column Statistics

Search, Sort & Analyze CSV Datasets Online. Fast in-browser CSV and TSV spreadsheet grid with column sorting, live search filter, and automated statistical analysis.

What is CSV Analyzer and what does it do?

The CSV Data Grid & Statistics Explorer is a high-speed tabular spreadsheet viewer that provides multi-column sorting, live search filtering, and automatic column statistics.

Inspect large CSV, TSV, and TAB files with zero server round-trips, ensuring sensitive company numbers and customer lists remain confidential.

  • Parse RFC-4180 CSV, TSV, semicolon, and pipe-delimited data tables.
  • Multi-column sorting (ascending/descending) and global row search.
  • Automated numeric statistics: mean, min, max, sum, and record counts.
  • Export sorted and filtered datasets as clean CSV files.

How does CSV Analyzer work?

Streams and splits text lines while respecting quoted fields and delimiters, computes column-level aggregations in memory, and renders paginated table grids.

100% private: all processing happens locally in your browser using client-side WebAssembly, WebCrypto, WebAudio, and HTML5 Canvas. Your files are never uploaded to any server.
