Turn a vertical Miro timeline into a horizontal project plan

Bring in the board, check what was read, then export a Gantt-style plan for decks, Miro or Excel. Everything runs in this page; nothing is uploaded.

Miro board items as JSON

How to get the JSON from Miro

Copy the board ID from its address: miro.com/app/board/uXjV…=/. Write the trailing = as %3D.
In Miro, open Settings → Your apps, create an app with boards:read, install it to your team and copy the access token. (Your Miro admin may need to allow this.)
Run: curl -H "Authorization: Bearer TOKEN" "https://api.miro.com/v2/boards/BOARD_ID/items?limit=50"
If the response has a cursor, run it again with &cursor=… added and paste each page in below the last.

Frames, sticky-note colours, positions, shape heights and card due dates are all used. Connectors and images are ignored.

Timeline as text or CSV

What the text can look like

Put each date or period on its own line (March 2026, Q2 2026, w/c 3 Mar, Sprint 4). Lines under it belong to that period.
Dates inside a line are used directly: Pilot 3–20 Mar 2026, Sign-off 27/03/2026.
A heading line (## Delivery or Delivery:) starts a new lane.
CSV or tab-separated rows with headers such as Task, Lane, Start, End are read as a table. Pasting from Excel works.

PNG drops straight onto a Miro board or a slide. SVG stays sharp and editable in PowerPoint (Convert to Shape). CSV opens in Excel, Smartsheet or MS Project.

The horizontal plan appears here after you convert.
