• Importers

• Faceting

• Editing:

  • Cell Editing, editing cells by Clustering
  • Column Editing, creating columns by Extending Data
  • Row Editing
  • Understanding Expressions
  • Understanding Regular Expressions

• Exporters

• History (undo/redo)

Reconciliation: You can use the "reconciliation" support in Refine to link text names in your data to database identifiers (also known as database keys, IDs). By connecting your data with other databases, you get more value out of your data.

• Reconciliation
• Reconcilable Data Sources
• Extending Data

Extensions: Add even more features to Refine by installing extensions.
