You can set breakpoints and use the Immediate Panel to inspect or modify values during debugging.
The Locals Panel also helps you track variable values at different stages.
Another option is to save DataTable values to an Excel or CSV file using the Write Range activity and reload them later with Read Range.
If using an Orchestration Process, you can store DataTables as queue items in Orchestrator and retrieve them when needed.
Happy Automation with UiPath.
