CoderHow to Use Coder
Install Coder, then follow these steps the first time you use it.
1. Install and Authorise
- Install Coder from the monday.com Marketplace.
- On a board, add a view: + → Apps → Coder.
- Press Authorise once: Coder can then work on QR codes and bulk actions for your account.
2. Assign Codes Automatically
Add a Text column for the codes, then in Automate → Coder choose Assign Unique Code with the trigger “When an item is created”. Set:
- Pattern: plain text plus tokens, e.g.
INV-{YYYY}-{SEQ:5}→INV-2026-00042. - Unique in: this board, this workspace or the whole account.
| Token | Generates | Example |
|---|---|---|
{SEQ:n} | Next number of the sequence, n digits | 0042 |
{RAND:n} | Random letters and digits (no 0, O, 1, I) | 7K2Q9X |
{NUM:n} | Random digits | 581 |
{HEX:n} | Random hexadecimal characters | 3FA0 |
{YYYY} {YY} {MM} {DD} | Date of creation | 2026 |
{ITEM_ID} {BOARD_ID} | monday item or board ID | 1843… |
{CHECK} | Check character that catches typing mistakes | F |
3. Validate Codes Typed by Hand
Add Validate Code with “When Code changes”. Choose what happens to an invalid code: clear it, put back the previous valid code, or keep it and set a status (first add a label such as “Invalid code” to your Status column). The person who typed it gets a notification.
4. Tools in the Coder View
- Check Existing Codes: codes that do not follow the pattern, repeat, or have a wrong check character.
- Check Uniqueness: repeated codes only.
- Assign Missing Codes: a code for every item without one; “Start Numbering From” skips numbers used before Coder.
5. QR Codes
- In the QR Codes tab, create a QR profile: the columns a scan changes, who can scan, what happens after scanning, and the text under the QR code.
- Create the QR codes with Create QR Codes (choose the Files column for the PNG files) or with the Create QR Code automation.
- Select QR codes and press Print: the labels open in a new tab.
- Scan with any phone camera: the item is updated and an update is posted on it.
Editing a profile changes what its printed QR codes do: no need to print them again. Revoking a QR code stops it working.
