The Scenario
You are the operations manager for a vendor onboarding program. Someone built a Google Sheet to track 60 new vendors — contract value, region, priority score, and the Trello list each vendor's card should land in. Your predecessor set up the Trello board with custom fields for exactly those three data points. The cards need to be created today.
The bad version:
- Create the first card in Trello manually, open the custom fields panel, type in contract value, pick the region from the dropdown, enter the priority score.
- Go back to the sheet, find the next vendor, repeat.
- Sixty vendors. Each with three custom field entries. That's 180 individual field edits, and you haven't even named the cards yet.
Custom fields exist to make Trello a structured database, not a sticky-note wall. But populating them manually from a spreadsheet defeats the purpose of having the structure at all.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the sheet, knows the Trello board's custom field definitions, and creates every card with the field values pre-populated.
For each row in this sheet, create a Trello card in the list ID in cell B1, then set the custom field 'Contract Value' to column C, 'Region' to column D, and 'Priority Score' to column E. Write the card ID into column F.
What You Get
- One Trello card per row, placed in the list specified by the ID in B1.
- Custom fields 'Contract Value', 'Region', and 'Priority Score' set from columns C, D, and E.
- The resulting card ID written into column F for future reference.
- Rows where a custom field value is blank are created with that field left empty, not skipped.
What If the Data Is Not Quite Ready
You don't know the custom field names exactly as defined on the board
Read the custom field definitions from our Trello board ID in cell A1 and list them in a new tab called 'Fields'. Then create cards from the main tab: use column A as name, and match columns B through E to the field names listed in the Fields tab by position.
Region values in the sheet use full country names but Trello expects region codes
For each row in this sheet, create a Trello card in list B1. Before setting the 'Region' custom field from column D, convert any full country name to its two-letter ISO code. Write card ID into column F.
Some rows are missing a contract value and should be skipped
Create Trello cards from this sheet for all rows where column C is not blank. Use column A as card name, column B as list name, column C as Contract Value, column D as Region, column E as Priority Score. Write the card ID or 'skipped — no contract value' into column F.
Validate the data, create the cards, and summarize errors in one pass
Check this sheet for rows where column C contains non-numeric values or column D is blank. Flag those in column G as 'invalid'. For all remaining rows, create a Trello card in list B1 with custom fields Contract Value (C), Region (D), Priority Score (E). Write card IDs into column F. At the end, add a summary row counting how many were created vs flagged.
One prompt handles the validation and the creation together — no pre-processing step needed.
