# Value formats, serial numbers, dates

> {{price|won}}, {{date|date:YYYY.MM.DD}}, {{seq:0001}}, {{today+365}}: change how values print without touching the data.

Source: https://82label.app/en/docs/formats/

Add `|format` after a field name to change how its value prints. The data stays as it is. In the designer, pick one from the "Format" list in the field table or in text and barcode properties.

| Write | Value | Prints |
| --- | --- | --- |
| `{{price\|money}}` | 12900 | 12,900 |
| `{{price\|won}}` | 12900 | 12,900원 |
| `{{date\|date}}` | 20261022, 2026-10-22, 45950 (Excel date) | 2026-10-22 |
| `{{date\|date:YYYY.MM.DD}}` | 2026-10-22 | 2026.10.22 |
| `{{date\|date:D/M/YY}}` | 2026-10-22 | 22/10/26 |
| `{{no\|pad:6}}` | 42 | 000042 |
| `{{code\|upper}}` · `\|lower` · `\|trim` |  ab-1  | AB-1 · ab-1 · ab-1 |

Date tokens: `YYYY` `YY` `MM` `M` `DD` `D` `HH` `mm` `ss`. An unknown format name leaves the value unchanged.

## Serial numbers and today

- `{{seq}}`: the label's position in this print (1, 2, 3…). With copies per row, every printed label counts.
- `{{seq:0001}}`: the digits give the start and the width. `0001` starts at 0001 with 4 digits, `0100` at 0100.
- Change the start with `print(t, rows, { serialStart: 501 })`, the same as "First number" on the bulk print page.
- `{{today}}`, `{{today+365}}` (best before), `{{today-1}}`: the print date in your time zone; `|date:FMT` works too.
- `{{now}}`: the print time as `YYYY-MM-DD HH:mm`.

```js
const template = {
  v: 1,
  name: 'Asset tag',
  paper: { kind: 'roll' },
  label: { width: 50, height: 25 },
  elements: [
    { type: 'text', x: 2, y: 2, w: 30, h: 5, text: '{{name}}', size: 8, bold: true },
    { type: 'text', x: 30, y: 2, w: 18, h: 5, text: '{{price|money}}', size: 8, align: 'right' },
    { type: 'barcode', x: 2, y: 8, w: 46, h: 15, format: 'code128', value: 'A-{{seq:0001}}', showText: true },
  ],
};

const rows = [
  { name: 'Laptop', price: 1290000 },
  { name: 'Monitor', price: 329000 },
];

Label82.print(template, rows);
```

> `extractFields(t)` returns data fields only: formats are stripped and `seq`, `today` and `now` are left out.
