Fast viewer
for data files
- Delimited text files (CSV, TSV, PSV, etc.)
- Binary files: QVD, Parquet, DSET
- Loads millions of rows in seconds
- Best for exploratory analysis of large data files
- Forever free! No strings attached
Query data, explore relationships in data, and spot oddities by using best-in-class filtering. CSViewer indicates values excluded from the current selection for a better insight into data.
Aggregates and charts are updated immediately when a filter is applied or changed.
Quickly understand data by instantly profiling the whole dataset, or any column, or even individual values. See uniques, spot outliers, and detect data quality issues at a glance.
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.
Don't waste time by configuring filters and charts from scratch when you open a file again. Save a view (a .csview file) and next time continue your analysis from where you left off. Easily switch the data source of a view to another file (e.g. to analyze another period in time).
