🧑‍💻 Regenerating the Data File

If the NBR publishes an updated audit list, regenerate audit_data.js from the new Excel file using this Python script:

import pandas as pd, json

df = pd.read_excel('AUDIT_SELECTION.xlsx', dtype={'tin': str})
data = {
    str(row['tin']).strip(): {
        'serial': int(row['#']),
        'tin': str(row['tin']).strip(),
        'zone': str(row['zone']),
        'circle': str(row['circle']),
        'submission_type': str(row['submission_type']),
        'assessment_year': str(row['assessment_year'])
    }
    for _, row in df.iterrows()
}

with open('audit_data.js', 'w') as f:
    f.write('const AUDIT_DATA = ' + json.dumps(data, ensure_ascii=False) + ';')

print(f"Done. {len(data)} records written.")

Then replace the old audit_data.js in the repo and commit — Netlify will auto-redeploy.
