Main Features
Automatic labeling of bank/payment emails
The Bank_Label function inspects sender/subject and applies Gmail labels based on user-defined bank codes.
Scheduled auto-deletion
Bank_AutoRemove moves login alerts and other low-value messages to Trash after a user-defined number of days.
Automatic archiving of transactions
Bank_AutoArchive archives processed transaction messages, keeping them searchable but out of the inbox.
Save e-statement attachments to Drive
Bank_AutoSave backs up e-statement attachments to a designated folder in Google Drive.
Usage Examples
Label bank notification emails
The snippet below sets your own bank list and invokes Bank_Label() to organize the inbox.
/**
* 1) Define the bank codes you use
* 2) Run Bank_Label() manually or via trigger
*/
function setupAndLabel() {
// Override the array defined in bank.gs
var BankList_Own = ['008', '013', '803']; // 008=Hua Nan, 013=Cathay, 803=Union Bank
// Label the latest 100 threads in the inbox (Bank_Label is implemented in the library)
Bank_Label();
}Add this to your Apps Script project and run setupAndLabel, or bind it to an hourly trigger for continuous automatic labeling.
