Add examples/fix_excel_format.js which uses the WelsonJS msoffice Office.Excel API to read rows from data/fulllist.xlsx (worksheet 2), extract company, reservation time, resource, port and bandwidth, and log each row. For each entry it generates a per-company card Excel file by opening card_format.xlsx, populating template cells (with sensible defaults for missing resource/port/bandwidth), saving as data/{company}_card.xlsx, and exporting main.
