CSViewer vs. ConvertCSV vs. Tad vs. dbForge Query Builder for SQL Server Comparison Chart

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.

​Tad is a free (MIT Licensed) desktop application for viewing and analyzing tabular data. It is a fast viewer for CSV and Parquet files and SQLite and DuckDb databases that support large files. It's a Pivot Table for analyzing and exploring data. Internally, Tad uses DuckDb for fast, accurate processing. Designed to fit into the workflow of data engineers and data scientists. Tad includes updates to DuckDb 1.0, the ability to export filtered tables as Parquet (as well as CSV), a fix for formatting numbers in scientific notation, and other minor bug fixes and dependent package upgrades. A packaged installer for Tad is available for macOS (x86 and Apple Silicon), Linux, and Windows.
