CSViewer
CSViewer is a fast and free Windows desktop application for viewing and analyzing large delimited text and binary data files, such as CSV, TSV, Parquet, and QVD. It can load millions of rows in seconds and offers advanced filtering, instant profiling with aggregates, null counts, and outlier detection. Users can export filtered data, save analysis views, and visualize data through charts and cross-tables. CSViewer is designed for easy exploratory analysis without sending data to the cloud. Aggregates and charts are updated immediately when a filter is applied or changed. Null counts, uniques, min/max values, aggregates, etc. for every column. Export the filtered subset of rows into another file for sharing or use in another application. Convert data from one file format to another, e.g. from CSV to QVD. When you export into the native for CSViewer .dset file format, data is saved together with filters and charts for your convenience.

Caxton
Caxton is a native macOS large file text editor and CSV editor in one: a workbench for logs, CSVs, TSVs, JSON, SQL dumps, and exports of any size. One app instead of a text editor, a spreadsheet, and a log viewer: open the file and work. Every delimited file opens as text and as a typed grid; edits in either view show in the other, and saving writes the same file back. Nothing is imported.
It memory maps the file instead of loading it into RAM. A 50 GB log (403 million lines) opens immediately with memory under 160 MB. A 10 million row CSV opens as a sortable grid in 4.4 s, past Excel's row limit. Methodology at caxton.app/docs/benchmarks.
Find and replace with exact counts, filters that keep line numbers, a log viewer mode with severity filters, file compare, 18 encodings, typed sorting, fill series, remove duplicates.
Built for data engineers, SREs, DBAs, and analysts. After the 7-day trial, opening, searching, and filtering stay free; a license adds editing and saving.
