Bitcoin Address Checker is a Python-based graphical user interface (GUI) application that allows users to validate and query Bitcoin addresses. The application reads a list of Bitcoin addresses from a file, validates them, and then fetches their transaction details from Blockchain.info. The results are displayed in a table and can be exported to a CSV file.

• Validate Addresses: Validate the format of the Bitcoin addresses.
• Query Blockchain Data: Query transaction details for the addresses from Blockchain.info.
• Display Results: Display the results in a sortable table within the GUI.
• Export Results: Export the results to a CSV file.
