Tabulens — table viewer for VS Code

Open DBF, Excel, SPSS, Stata, Parquet, SQLite, Access and 20+ other table formats right in the editor. Double-click the file in the Explorer and you get a table: filter, search, group, build a pivot table, compare two files, check values and export to Excel or CSV.

Files are read from your disk by VS Code itself and processed inside the editor tab. Nothing is uploaded anywhere — there is no server involved at all.

A DBF file open as a table, with file details on the left and column statistics on the right

Formats

Opens by default	Open with “Open With… → Tabulens (table view)”
DBF (dBase, FoxPro, Visual FoxPro, Clipper — with .fpt/.dbt memo and .cpg encoding), DATASUS .dbc, Excel .xlsx/.xls/.xlsb, ODS, Parquet, SQLite and GeoPackage, Microsoft Access .mdb/.accdb, 1C .mxl, SPSS .sav/.zsav, Stata .dta, SAS transport .xpt, Norma 43	CSV, TSV, fixed-width text, JSON / JSON Lines, GeoJSON, XML (including SEPA camt.053, pain.001 and SAF-T templates)

Text formats keep opening in the normal text editor; Tabulens is one right-click away (Open in Tabulens in the Explorer context menu or the command palette).

What you can do

Scroll millions of rows; filter by column, search, sort.
Group with totals, build pivot tables and charts.
Compare two tables by key and see every changed field.
Check values (email, IBAN, dates, custom patterns), find duplicates, clean up text-as-numbers.
Read value labels in SPSS and Stata files; see variable labels as column descriptions.
Edit DBF, CSV, Excel, ODS, XML, JSON and SQLite tables and save them in place — a DBF together with its .fpt/.dbt memo file. Tabulens asks before overwriting.
Compare with Git HEAD: see what changed in a table since the last commit, row by row and field by field (button in the editor title, or right-click the file).
When the file changes on disk (git checkout, another program), Tabulens offers to reload it.
Export to Excel, CSV or JSON (Pro: also ODS, SQL, DBF, Parquet, HTML, Markdown).

Free and Pro

The extension is free, with the same limits as the web app: export up to 5,000 rows at a time, printing up to 200 rows, 3 open tabs. A Pro license ($29, once) lifts the limits — the same key works in the browser, the Windows program and VS Code. You can try Pro for 14 days with just an email.

Notes

Files must be saved on disk (local or remote workspaces). Unsaved and virtual files are not supported.
Compare with Git HEAD needs Git installed and the file committed at least once.
