Workflow Overview

PyIndexGUI enforces a strict, sequential data pipeline. Each tab consumes the output of the previous one, so you generally work left-to-right:

flowchart LR
    A[Data Import] --> B[Aggregation]
    B --> C[Panel Balancing]
    C --> D[Index Calculation]
    D --> E[Export]

Step	Tab	Purpose
1	Data Import	Load a file, map columns, standardize types.
2	Aggregation	Collapse observations into regular time periods.
3	Panel Balancing	Build a complete, balanced product-period panel.
4	Index Calculation	Compute bilateral and/or multilateral indices.
5	Export	Save results to CSV or Excel.

Tab navigation & prerequisites

Tabs are gated: you cannot move to a later stage until its predecessor has produced output. For example:

• You cannot Aggregate until columns have been standardized.
• You cannot compute Indices until the panel has been balanced.
• You cannot Export until at least one index has been calculated.

If you re-run an earlier step (e.g. re-standardize with a different mapping), all downstream results are automatically invalidated and you must repeat the affected steps.

The Info tab is always available

The Info tab has no prerequisites — you can open it at any time, even on a fresh launch with no data loaded.
