data-extraction-sync

Data extraction from non-standard Excel layouts uses structured mapping patterns to interpret visual arrangements and convert them into reliable data structures. This skill applies VBA-based layout mapping to pull data from whiteboard-like sheets, calendars, and matrix formats across multiple sheets, enabling automated parsing without manual reorganization.

Multi-sheet synchronization detects changes between source and target sheets, then propagates updates with validation and optional rollback. This skill implements bidirectional change tracking, so edits in any related worksheet are identified and safely applied across the workbook while maintaining data consistency.

Change detection identifies differences between sheets using structured comparison patterns, then applies updates through validated rules. This approach isolates which cells changed, validates them against business rules, and rolls back if validation fails, preventing silent data corruption across workbooks.

Yes, this skill uses VBA macros to enable automated extraction, change detection, and safe propagation across sheets. The workbook includes macro patterns for data typing, layout interpretation, and synchronization logic that execute when you run the provided macros after enabling them in Excel.

Bidirectional synchronization maintains consistency regardless of which sheet receives edits. The skill detects changes originating from any related sheet, applies validation rules, and propagates updates back, so your whiteboard and detail rows stay aligned whether users edit one or the other.
