When sharing and copying a workbook as a template, only the structure (columns/headers) gets copied, not the data. To preserve your data, you'll need to: 1. Share the template:
• Click "Actions" button
• Select "Share as template"
• Click "Turn on sharing"
• Copy the public link
2. After copying the template to the new workspace, you can transfer the data using the Write to Table integration:
• Click "Add Enrichment" in the top right corner
• Search for and select "Write to Table"
• Map your existing data fields to the corresponding columns in your new table
