The Scenario
The ping came in Monday morning: the project director had renamed your priority taxonomy over the weekend. What was "P1 / P2 / P3" is now "Critical / High / Normal." Twelve labels. One Trello board. Someone has to touch every single one.
You open the board. The labels are right there in the sidebar. Twelve of them.
The bad version:
- Open Trello board settings, click Labels, click the first label, retype the name, save.
- Repeat for the other eleven — navigating in and out of the label editor each time.
- Discover partway through that two labels share a color and you've lost track of which one you renamed.
Twelve labels takes maybe twenty minutes by hand, but this is the third taxonomy refresh in eight months. The time isn't the issue. The issue is that this is categorically not what you were hired to do.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the data in your spreadsheet, connects to Trello on your behalf, and can update labels, cards, boards, and members — all from a single prompt in the sidebar.
Start with a sheet that has label IDs in column A, old label names in column B, and new names in column C. Then:
Get all labels from the Trello board ID in cell A1, write their IDs, names, and colors into this sheet starting at row 2, then rename each label to the value in column C of the same row.
Or, if you already have the mapping built:
For each row in this sheet, find the Trello label with the ID in column A and rename it to the value in column B. Write "updated" into column C when done.
What You Get
- Every label on the board renamed to the new value from column C.
- Column C (or your chosen writeback column) populated with "updated" for each successful rename.
- Any rows where the label ID wasn't found on the board flagged in the writeback column rather than silently skipped.
- The board-level label list in Trello now reflects the new taxonomy immediately — no cache refresh needed.
What If the Data Is Not Quite Ready
The label IDs are missing — you only have old names
Get all labels from the Trello board ID in cell A1 and write their ID, name, and color into columns A, B, and C of this sheet. I'll fill in column D with the new names manually before the next step.
Run this first, fill in your new names, then rerun the rename prompt against the completed sheet.
Two labels share the same color and the names collide
Get all labels from the board ID in cell A1 and write ID, name, and color into this sheet. For any two rows with the same color value in column C, write a note in column D so I can decide which rename to apply first.
Surfacing the collision before you write is cheaper than untangling it after.
You need to rename labels across multiple boards, not just one
For each board ID in column A of this sheet, get that board's labels and write each label ID, name, and color as new rows in a second tab called "Labels." Then rename any label whose name in column B matches a value in column D to the corresponding value in column E.
The full cleanup plus rename in one shot
Get all labels from the board ID in cell A1. Write each label ID, name, and color into this sheet. Remove any label with no cards assigned to it. Then for each remaining label, rename it to the value in column C if column C is not blank.
One prompt does the audit, the pruning, and the renaming without a second pass.
Whenever cleanup and action can happen in the same instruction, write them together — you get one confirmation instead of two separate rounds of back-and-forth.
Try It
Open any Google Sheet that has a Trello label mapping — even a rough draft with board ID in one cell and new names in a column — then Get the 7-day free trial of SheetXAI and ask it to rename the labels in one pass.
