- Compare Datasets, redesigned. ID variables, the base data set and the compare data set sit side by side in three panes. The comparison runs in the background. Filters show variables and rows by kind: same, different, base only, compare only. - Faster previews. Workspace previews open instantly and page through every row. You can jump to any row or column (Quick Open: "r 1200 c AGE"). - Smarter SAS editor: - Code folds by program structure (steps, macros, DO blocks, comments), with Fold to Level 1–9. - Run Current (Ctrl+Enter) picks exactly the step, macro or statement at the cursor. - The code checker reports far fewer false alarms. - Text files keep their encoding (including WLATIN1 and GBK), line endings and BOM when you save. - Compare Files opens in its own window: aligned, faster, and safe when saving. - Markdown: open .md files in a rendered view, and copy table selections as Markdown tables. - Faster filtering on large data sets, many StatScript compatibility improvements, and bug fixes.

StatDataViewer 2.5 is our biggest update yet — introducing Stat Studio, an optional in-app upgrade that turns the viewer into a complete statistical programming environment. • Write and run SAS language programs with the built-in StatScript engine — no external software required • Connect to your own SAS Enterprise Guide or SAS Studio session (including SAS OnDemand for Academics) and submit programs, browse libraries, and open datasets directly • New: Connect to R — run R programs and an interactive R console against a local or remote Rserve session, with a live workspace browser • Emacs editing mode with code folding, keyboard macros, and familiar keybindings • Excel improvements: switching between worksheets is dramatically faster, each sheet now remembers your column layout, and row heights are adjustable • Frequency panel keeps your place in the data table, so you can analyze column after column without extra clicks • Many refinements and fixes throughout — including cleaner dataset tab names, a library Refresh command for connected SAS Studio sessions, and setup guides linked right from each connection dialog The core viewer remains free: open SAS, SPSS, Stata, R, Excel, and CSV files with filtering, frequencies, and descriptive statistics — no account, no upload, your data never leaves your Mac.
