Trello CSV: Export Boards and Import Cards from Spreadsheets

Trello Boards Still Escape into Spreadsheets

Lightweight ops and marketing teams across the US, UK, Australia, Canada, and Europe live in Trello until someone needs Excel. CSV exports capture cards for reporting; imports (via Power-Ups, Atlassian tools, or migration utilities) seed boards from sheets. List names, labels, and due dates must be deliberate — or cards land in the wrong column.

Export vs Import Jobs

Clarify the goal.

Step-by-Step: Export a Board for Stakeholders

Status pack path.

• Open the board you want to share.
• Use Trello’s export options available on your plan (CSV/JSON).
• If you receive JSON, flatten to CSV with a converter or script — or export CSV directly when offered.
• Archive raw as board-trello-YYYY-MM-DD.csv.
• Preview in Online CSV Editor; keep card IDs as text.
• Convert to Excel for leadership decks.

Step-by-Step: Import Cards from CSV

Backlog seed path.

• Create destination lists on the board first (To Do / Doing / Done).
• Build a rectangular CSV with Card Name + List columns.
• Prefer ISO due dates.
• Map members to emails that exist on the board.
• Standardize label names before import.
• Clean in Online CSV Editor; remove blank titles.
• Run the importer your Workspace supports; pilot 10 cards; then finish.

Lists, Labels, Checklists, and Attachments

What CSV handles poorly.

• List name typos create unexpected columns.
• Labels are case-sensitive in practice — standardize casing.
• Checklists/attachments usually need UI or API follow-up.
• Card descriptions with newlines need proper CSV quoting.

Dates Across US/UK/EU Teams

Due dates are locale bait.

• Prefer YYYY-MM-DD in handoff files.
• If Excel rewrites dates after export, clean before re-import.
• German semicolon CSV: convert delimiters first.

Trello vs Jira vs monday vs ClickUp

Same spreadsheet energy; different contracts.

• Trello: list/card simplicity.
• Jira: issue types/workflows — use Jira CSV import for tickets.
• monday/ClickUp/Asana: richer field typing on import.
• Keep a master delivery sheet if work is multi-homed.

Common Mistakes

Board clutter classics.

• Importing without a List column.
• Weekly re-imports without an ID strategy → duplicate cards.
• Exporting one filtered view and calling it the whole board.
• Expecting Power-Ups/Butler rules to travel in CSV.
• Emailing unredacted board exports with customer PII.

Best Practices

Make CSV a controlled intake.

• Maintain a template sheet for recurring imports.
• Version exports with board + date.
• Pilot every new importer mapping.
• Normalize member emails from your directory.
• Cleanse in-browser when agencies touch client boards.

Why Use Convert CSV Online?

Convert CSV Online is free, browser-based, and requires no account for everyday conversions. Flatten and preview Trello exports in the Online CSV Editor, fix dates/delimiters, and convert to Excel or Markdown for stakeholders across US, UK, AU, CA, and EU teams.

Conclusion

Trello CSV works when card titles, lists, labels, and dates are deliberate. Export for reporting, import with pilots, and treat CSV as a bridge — not a backup of Butler, Power-Ups, and attachments.
