What is JSON/CSV Importer?
JSON/CSV Importer is a Trello Power-Up that turns CSV, JSON, XLS, and XLSX data into Trello cards and lists. Users can map title, list, description, and extra source fields, preview the imported rows, and follow progress.
How to import data into Trello
Upload, map, and create the board structure.
The importer keeps each decision visible, so you can confirm how file fields and records will become Trello content.
Map fields to Trello
Connect source columns or properties to card titles, descriptions, and list placement.
Run and follow the import
Create the Trello cards with visible progress and clear error feedback.
Import details
Know how source records become Trello cards.
Source files
Upload CSV, XLS, or XLSX for spreadsheet-style rows, or JSON for structured records.
Card titles
Map the source field containing each task or record name to the Trello card title.
Descriptions
Move longer source text into the card description instead of copying it manually.
List placement
Use a source status or stage field to control where imported cards belong on the board.
Preview and progress
Review the field mapping and sample records, then follow visible progress and error feedback during import.

Trello importer questions
Bring existing CSV or JSON data into Trello.
Can I import CSV into Trello?
Yes. Upload a CSV file, map source columns to Trello fields, preview the records, and create cards in the selected board.
Can I import JSON into Trello?
Yes. Upload a JSON file, map source properties to Trello fields, preview the records, and create cards in the selected board.
Can I import Excel into Trello?
Yes. JSON/CSV Importer accepts XLS and XLSX workbooks in addition to CSV and JSON files.
Can I map source fields before importing?
Yes. Map the card title, list, description, and optional extra source fields before import.
Can I preview an import before applying it?
Yes. The import workflow shows detected fields, sample records, the selected mapping, and progress before and during card creation.
What Trello objects can be created?
JSON/CSV Importer creates Trello cards and can create missing lists when that option is enabled.
What happens if some source fields cannot be mapped?
A row without a usable card title is skipped. If a mapped list does not exist and list creation is disabled, that row is skipped. Unselected fields are not created as separate Trello fields, while selected extra fields can be added to the card description.
