Inspect an Attribute Table in Your Browser

Learn how to open GIS files in GeoDataViewer and inspect the attribute table to validate fields, values, and feature counts.

When you open a GIS dataset, the map is only half the story. The attribute table contains the fields and values you usually need to validate: IDs, names, classifications, dates, and other metadata.

GeoDataViewer lets you inspect attributes locally in your browser, without uploading your data to a server.

Step-by-step

  1. Open the Studio: /studio/
  2. Drag and drop your file into the viewer.
  3. Open the data panel and browse the attribute table.
  4. Sort or scan fields to confirm expected values and feature counts.

Format-specific notes

  • Shapefile attributes are stored in the .dbf sidecar file. If attributes look empty, ensure the .dbf was uploaded together with .shp and .shx.
  • GeoJSON stores properties directly in the file.
