Data is rendered as a readable grid of rows and columns rather than a wall of comma-separated text.
Handles the two most common tabular interchange formats, covering both lightweight CSV exports and compact columnar Parquet files.
The viewer is backed by Tab Lab's analytics workspace, which layers AI-driven exploration on top of the raw data.
CSV and Parquet Viewer is a browser extension built by Tab Lab. Its job is narrow and practical: when you land on a page that links to a .csv or .parquet file, the extension offers to open that file in the Tab Lab environment instead of dumping a raw download into your folder. The data appears as a structured table you can scroll, sort and explore.
Filtering is the core of the experience. Rather than eyeballing thousands of rows in a plain text editor, you can narrow the dataset interactively and inspect specific columns, which makes quick sanity checks much faster. The listing also describes AI-assisted analysis, positioning the extension as an entry point into Tab Lab's broader analytics workspace rather than a standalone offline tool.
The extension is small (about 114 KiB) and installs in seconds from the Chrome Web Store. Because it is a thin client for the Tab Lab web app, an internet connection is generally needed for the full analysis experience. The developer states in the store listing that no user data is collected or sold, and the current published version is 0.0.3.
Open a CSV or Parquet file linked in a report or ticket and confirm row counts, column names and value ranges before importing it into a full pipeline.
Click through to a data export and filter it visually, answering a business question without waiting on an engineer to run a query.
Check the schema and a sample of a columnar file from the browser instead of spinning up a local toolchain just to look at it.
Browse public CSV datasets on the web and narrow them down interactively while you decide which subset is worth downloading.
