Importing Data

Bring your existing data into Stacker from spreadsheets, CSV files, or other sources.

Supported Formats

Comma-separated values

.xlsx and .xls formats

In your app, open Setup → Data to see your tables and start an import

Select the table you want to import into, or create a new one

Drag and drop or browse for your CSV/Excel file

Match your file columns to table fields, or let AI auto-map them

Preview the data and click Import to bring it into your table

Ensure your spreadsheet has headers in the first row

Clean your data before importing (remove duplicates, fix formatting)

Use consistent date formats (YYYY-MM-DD works best)

For relations, include the name or ID of the linked record

Start with a small test import to verify mappings
