Dynamic Search and Automated Report Generation

This n8n workflow creates a dynamic search interface that allows users to query suspicious banking transactions efficiently. Users fill out a form specifying a minimum transaction amount, a time range, an optional customer ID, and preferred report format (Text or CSV). The workflow then constructs an Elasticsearch query based on these inputs, executes the search on the bank transactions index, and processes the results into a human-readable report or CSV export. The generated report is saved to disk with a timestamped filename for easy retrieval and compliance documentation. This automation is particularly useful for fraud monitoring, compliance audits, or investigative tasks within banking or financial institutions.
