TL;DR Ask
Build a Claude Data dashboard from data/tips.csv. Claude uploads the file, writes the calculations and gives you the link. Open Sources and click a figure to see its formula and its rows. Anyone who can open the dashboard can read the whole file.
Claude Data has been, since November 10, 2026, the new name of Claude Dashboards, and it is out of beta on every paid plan. It does the same thing: a page of charts and figures that works itself out again each time someone opens it. The announcement says it needs a data connector. From Claude Code there is another way in that the announcement leaves out: an attached file. This dashboard was built from a CSV and no connector.
What comes out
The CSV has one row for each tip published on wmedia.es: number, date and topic. From that, Claude built this dashboard:
Redrawn from the real dashboard.
It took three calls: creating the dashboard, uploading the file, and one batch with the title, the source and the page. It loaded without errors the first time, with 265 rows read.
Every figure says where it comes from
This is what sets it apart from an HTML page with charts. The Sources button opens a panel with the file and the five calculations Claude wrote. With it open, you click a figure and see where it comes from:
No figure is typed by hand into the page. Anyone who doubts the 265 can check it without asking you.
How to ask for one
1. Have the CSV in the repo
A CSV, a TSV or a JSON file will do. A CSV split by semicolons loads as a single column: convert it to commas first.
2. Ask for the dashboard
Build a Claude Data dashboard from data/tips.csv
3. Open Sources and read the calculations
Each calculation is a short function anyone can read, such as (tips) => tips.length.
4. Ask for changes by name
Add a filter by topic and a chart of tips per month
5. Upload the file again when it changes
An attached file is a copy. The dashboard doesn't know the CSV in your repo has changed until you ask Claude to upload it again.
File or connector
| Attached file | Live query | |
|---|---|---|
| Where the data comes from | A copy Claude uploads | A claude.ai connector |
| When it updates | When you upload it again | Each time someone opens the dashboard |
| Who sees the data | Everyone who can open the dashboard, the whole file | Each reader, with their own access |
| What it is for | A one-off report, data that doesn't change | A dashboard you check every week |
If your data lives in a service with a connector, a live query is the better option, and for that you need a claude.ai connector, not a local MCP.
What changes with the name
- It leaves beta: available on every paid plan.
- Data stories: a page that tells the data in order, in place of a dashboard.
- Certified queries (beta): the data team marks a query as the official one.
- Live sharing (beta): you share your connector and others see the numbers without access to the database.
- Enterprise: on by default from November 19, 2026.
If what you want is to edit the figures by hand and not only look at them, that is a Claude Sheets sheet.

Requirements: a paid plan, signed in with a claude.ai account (/login). An attached file needs no connector.
