    • The minified version of this module is 2.4KB.
    • The only dependency is printf, which can be minified to 8.2KB
    • The source code of aba-generator is quite easy to read, understand, and amend. We welcome any changes.



    npm i -S aba-generator

    Minimal example of sending money from your account:

    const ABA = require("aba-generator");
    const aba = new ABA({
      bank: "ANZ", // The bank processing this file
      user: "Allowasa Pertolio Accounting&Tax", // Your (money sender) company name
      userNumber: 1234, // Your ID in the bank system, often hardcoded to some number. Consult with your bank
      description: "Credits Of The Wooloomooloo" // Description of the transactions within the file
    // Optional
    // bsb: String, // Main account BSB. Not in the ABA spec, but required by ANZ
    // account: String, // Main account number. Not in the ABA spec, but required by ANZ
    // date: Date|String|Number, // The date to be processed, default is now
    // time: Date|String|Number, // The time to be processed. Not in the ABA spec, but required by ANZ
    const transaction = {
      bsb: "061021", // recipient's account BSB
      transactionCode: ABA.CREDIT, 
            // indicates "you are sending money (debit), they are receiving (credit)". ABA.PAY works in the same way but with code 53 
      account: "123456", // recipient's account number
      amount: 12.0, // Number|String sending amount the recipient will see in their bank account
      accountTitle: "Georgian Council of New South Wales", // recipient account name
      reference: "Invoice # 1234", // payment reference, will be visible to the recipient
      traceBsb: "061123", // your (sender) bank account BSB
      traceAccount: "1234567", // your (sender) bank account number
      remitter: "Acme Inc" // Your (sender) company name
    // Optional
    // tax: "N"|"W"|"X"|"Y"|" "|"", // Tax withholding indicator. Typically blank, meaning no tax. See ABA specification.
    // taxAmount: Number|String, // Tax amount. Typically 0.
    const file = aba.generate([transaction]);

    Should print:

    0                 01ANZ       Allowasa Pertolio Accounti001234Credits Of T180320                                        
    1061-021   123456 500000001200Georgian Council of New South WaInvoice # 1234    061-123  1234567Acme Inc        00000000
    7999-999            000000120000000012000000000000                        000001                                        

    which is a fully valid ABA file. Note spaces in the end of the first and last lines.

    Every line in the ABA file must be 120 chars. So data like user, description, accountTitle, etc are truncated if too long.


    Even though the format is standardised, banks typically mandate some fields to be hardcoded.
