ABA generator
Generate ABA Files from Node.js and browser.
Notable:
- The minified version of this module is 4.2kb. No dependencies.
- The source code of
aba-generator
is quite easy to read, understand, and amend. We welcome any changes.
Changes between v1 and v2
- BREAKING: header options were
options: { ...headerData }
, become options: { header: headerData }
. - Added support of non-standard ABA files.
Usage
Installation
npm i -S aba-generator
Minimal example of sending money from your account:
const ABA = require("aba-generator");
const aba = new ABA({
header: {
bank: "ANZ",
user: "Allowasa Pertolio Accounting&Tax",
userNumber: 1234,
description: "Credits Of The Wooloomooloo",
},
});
const transaction = {
bsb: "061021",
transactionCode: ABA.CREDIT,
account: "123456",
amount: 12.0,
accountTitle: "Georgian Council of New South Wales",
reference: "Invoice # 1234",
traceBsb: "061123",
traceAccount: "1234567",
remitter: "Acme Inc",
};
const file = aba.generate([transaction]);
console.log(file);
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.
Note
Even though the format is standardised, banks typically mandate some fields to be hardcoded.

Custom transaction generating
You can add multiple custom schemas or replace default schemas to generate non-standard ABA files or those extended by a particular bank.
Keys description
N
- is a string key with one character, that represents the first character in the ABA record,
for default schemas ("0" - Descriptive Record (header), "1" - Detail Record (transaction), and "7" - File Total Record (footer)).
Keep in mind that all ABA strings begin with this number and that the field name: "type"
in the provided data and custom schema must be the same as N
in the schema.
recordType
- a string that identifies the batch's record type.
Descriptive Record -> header; Detail Record -> transaction; File Total Record -> footer
name
- the name of a field (amount, tax, etc.).
boundaries
- array with 2 numbers, that specify the start and end of the field in the record string.
padding
- Alignment within field size, can be left
or right
, and only for type string
, default alignment is to the right
type
- type of the field, provide the desired type to reformat the field.
Possible types:
string
– trim spaces and return the string
money
- convert cents to dollars and return the number.
integer
- trim all 0
in the start and return the number
bsb
- remove "-" and return the string
""
– retrieve the original string
customSchemas = {
N: {
recordType: "header" | "transaction" | "footer",
fields: [
{
name: "string",
boundaries: [number, number],
type: "string" | "money" | "integer" | "bsb" | "",
padding: "left",
},
],
},
};
const aba = new ABA({ header: headerData, schemas: customSchemas });
Attention! In order to generate standard footer you must have at least these transaction fields
fields: [
{ name: "transactionType", boundaries: [0, 1], type: "string" },
{ name: "transactionCode", boundaries: [18, 20], type: "integer" },
{ name: "amount", boundaries: [20, 30], type: "money" },
];
Custom schema use example
const customSchemas = {
5: {
recordType: "transaction",
fields: [
{ name: "transactionType", boundaries: [0, 1], type: "string" },
{ name: "bsb", boundaries: [1, 8], type: "bsb" },
{ name: "account", boundaries: [8, 17], type: "string" },
{ name: "transactionCode", boundaries: [18, 20], type: "integer" },
{ name: "amount", boundaries: [20, 30], type: "money" },
{ name: "traceBsb", boundaries: [80, 87], type: "bsb" },
{ name: "customString", boundaries: [120, 135], type: "string" },
{ name: "customInt", boundaries: [135, 140], type: "integer" },
{ name: "customBsb", boundaries: [140, 145], type: "bsb" },
{ name: "custom", boundaries: [145, 150], type: "" },
{ name: "customBsb", boundaries: [155, 160], type: "bsb" },
{ name: "customMoney", boundaries: [165, 170], type: "money" },
],
},
6: {
recordType: "header",
fields: [
{ name: "type", boundaries: [0, 1], type: "string" },
{ name: "bsb", boundaries: [1, 8], type: "bsb" },
{ name: "account", boundaries: [8, 17], type: "string" },
{ name: "custom", boundaries: [145, 150], type: "" },
],
},
};
const aba = new ABA({
header: { type: "6", custom: "any", bsb: "123456", account: "12345678" },
schemas: customSchemas,
});
const batches = aba.generate([transactions]);
Default schemas
Here the list of standard schemas, you can rewrite them with custom types by using the same key
const defaultAbaSchemas = {
0: {
recordType: "header",
fields: [
{ name: "type", boundaries: [0, 1], type: "string" },
{ name: "bsb", boundaries: [1, 8], type: "bsb" },
{ name: "account", boundaries: [8, 17], type: "string" },
{ name: "sequenceNumber", boundaries: [18, 20], type: "integer" },
{ name: "bank", boundaries: [20, 23], type: "string" },
{ name: "user", boundaries: [30, 56], type: "string", padding: "left" },
{ name: "userNumber", boundaries: [56, 62], type: "string" },
{ name: "description", boundaries: [62, 74], type: "string", padding: "left" },
{ name: "date", boundaries: [74, 80], type: "string" },
{ name: "time", boundaries: [80, 84], type: "string" },
{ name: "filler", boundaries: [84, 120], type: "string" },
],
},
1: {
recordType: "transaction",
fields: [
{ name: "transactionType", boundaries: [0, 1], type: "string" },
{ name: "bsb", boundaries: [1, 8], type: "bsb" },
{ name: "account", boundaries: [8, 17], type: "string" },
{ name: "tax", boundaries: [17, 18], type: "string" },
{ name: "transactionCode", boundaries: [18, 20], type: "integer" },
{ name: "amount", boundaries: [20, 30], type: "money" },
{ name: "accountTitle", boundaries: [30, 62], type: "string", padding: "left" },
{ name: "reference", boundaries: [62, 80], type: "string", padding: "left" },
{ name: "traceBsb", boundaries: [80, 87], type: "bsb" },
{ name: "traceAccount", boundaries: [87, 96], type: "string" },
{ name: "remitter", boundaries: [96, 112], type: "string", padding: "left" },
{ name: "taxAmount", boundaries: [112, 120], type: "money" },
],
},
7: {
recordType: "footer",
fields: [
{ name: "type", boundaries: [0, 1], type: "string" },
{ name: "bsb", boundaries: [1, 8], type: "bsb" },
{ name: "netTotal", boundaries: [20, 30], type: "money" },
{ name: "creditTotal", boundaries: [30, 40], type: "money" },
{ name: "debitTotal", boundaries: [40, 50], type: "money" },
{ name: "numberOfTransactions", boundaries: [74, 80], type: "integer" },
{ name: "filler", boundaries: [80, 120], type: "string" },
],
},
};
In the end your code can look like this
const { ABA } = require("aba-generator");
const aba = new ABA({ header, schemas: { customSchema } });
const batch = aba.generate(transactions);
.generate(transactions)
Transactions schema. Most of the params are required as you can see.

* @param transactions {Object[]} Transactions in the file
* @param transactions[].bsb {String} The third party account BSB
* @param [transactions[].tax=" "] {"N"|"W"|"X"|"Y"|" "|""}

* @param transactions[].traceBsb {String} The transacting account BSB
* @param transactions[].traceAccount {String} The transacting account number
