Duplicate Detector scans a monday board, groups items that refer to the same thing, and lets you merge, archive, delete or ignore them — without ever changing anything on its own. The app is available in English and French (it follows your monday language, and you can switch with the EN/FR toggle in the header).
1. Installation
- Install the app from the monday marketplace (or your install link).
- Open the board to clean → + tab → Apps → Duplicate Detector.
- The view is added as a board tab. On first open, click Connect monday: an OAuth window opens, approve it — done. No API key to paste. The connection covers your whole account.
2. Run a first scan
Click Run scan. By default, two items are duplicates when their names are equivalent (same letters ignoring case, accents and punctuation).
Scanning is 100% read-only: it never modifies, archives or deletes anything. Safe to run on a production CRM.
Each group shows a confidence level (Almost certain / Very likely / Likely), the items, and the suggested item to keep (the master, highlighted row).
3. Configure detection rules (Settings)
Compared fields
Check the item name and/or up to 5 columns (text, email, phone, link, numbers, date, status, dropdown, people, country). All checked rules must match (logical AND). Per-field strategies:
| Strategy | Use it for |
|---|---|
| Equivalent (default) | Ignores case, accents, spacing, punctuation. Jean DUPONT = jean dupont. Gmail dots/+tags match, +33 6… = 06…, links compared without utm_… parameters |
| Identical | Strict character-by-character match |
| Fuzzy | Typo-tolerant match (text only, adjustable 70–95% threshold) |
Columns displayed in results
Check up to 10 display-only columns: they are added to the results table (on top of the compared fields) to help you decide which item to keep — they never affect detection. Visible from the next scan.
Scanned groups
No selection = whole board. Otherwise the scan is limited to checked groups (duplicates ACROSS checked groups are detected).
Default kept item (master)
Up to 3 ordered priority rules — “column X is filled”, “column Y equals Z” (e.g. Status equals Signed client) — then the tie-breaker: most complete, oldest, or most recently updated.
4. Resolve a duplicate group
- Master: change the kept item with one click (radio button).
- Keep: check extra items to preserve untouched alongside the master.
- Merge into master: fills every empty master field from the duplicates (values re-read live at merge time), posts a traceability update on the master, then archives the duplicates. Nothing is deleted.
- Archive: archives the duplicates, master untouched.
- Delete: real deletion — protected by a second confirmation click.
- Ignore (not a duplicate): remembers the pairs; they will never be flagged again (resettable in Settings).
Bulk actions: merge or archive every open group at once, with per-group exclusions (“Exclude from bulk action”). Large operations run in the background with a live progress bar; a fresh scan starts automatically afterwards to reflect the real board state.
