Learn how to work with uploaded datasets in the transformation workspace-open a dataset, preview data, and manage multiple tables at once.
Once a file is uploaded, Supabind opens it in the transformation workspace, where every sheet becomes a table you can preview, rename, and work with independently. You can bring in multiple tables at once, switch between them as your active working table, and remove any you no longer need-all without leaving the workspace.
Open any previously uploaded file to load it into the transformation workspace.
Opening a dataset doesn't modify the original file. Changes you make in the workspace are saved separately until you choose to export or overwrite the source file.
Preview the first rows of a table to confirm headers, column types, and data quality before running any transformations.

Supabind automatically infers column types like text, number, and date so you know what you're working with.
The preview header shows total rows and columns so you can confirm the full file imported correctly.
Every sheet in an uploaded workbook appears as its own table in the workspace sidebar. Rename a table, reorder tables, or open multiple tables side by side to compare data before merging or transforming.
Bring in additional tables from other uploaded files without leaving your current workspace-useful when you need to merge or cross-reference datasets.
When multiple tables are open, only one is active at a time. Transformations, filters, and charts apply to the active table. Click a table name in the sidebar to make it active-its contents load into the main workspace and any others stay available in the background.
Remove a table from the workspace when you no longer need it. This only removes it from your current working session-the original uploaded file is not deleted.
Removing a table won't affect any transformations already saved as a template. If a merge depends on the table you're removing, Supabind will warn you before continuing.
