Power-Ups for Trello
Small tools for Trello that do one job properly
Each one shows you what it will do before it does it, keeps your data in Trello, and costs one flat price for your whole workspace.
Available now
Spreadsheet Importer
Import a CSV or Excel file into a board. Rows that match a card update it, the rest become new cards, and you can undo the lot.
Updates the cards you already have
Match rows to cards by a custom field of your own, such as an order number, or by card name, number or link. Import the same sheet every week and nothing is added twice.
Shows every change first
For each card you see the field, what it holds now and what it will hold after. Nothing is written until you have looked and said so.
Undo a whole import
Every changed field goes back to what it was. Cards the import added are archived, not deleted. A field someone has edited since is left alone and listed for you.
Touches only what you match
An empty cell changes nothing. Type [clear] to empty a field. Comments, checklists, attachments and unmatched fields are never touched.
Reads real spreadsheets
Excel and CSV, including semicolon-separated files and files saved by older versions of Excel. Dates are read as dates, day-first or month-first.
Built for big files
Five hundred new cards take about three minutes and updates are several times faster. If your connection drops, carry on where it stopped without creating anything twice.
How these are made
Things you can rely on
Your data stays between you and Trello
Boards are read and changed in your own browser, talking straight to Trello. Card data and spreadsheets do not pass through our servers.
Nothing hidden in your cards
No markers written into descriptions or comments to make a Power-Up work. What you see on the card is what is there.
One price per workspace
Every board and every member is covered. You never have to work out who has a seat.
