Excel Data Source

Learn how to structure your Excel files for merging with PowerPoint templates.

Basic Structure

Your Excel file (.xlsx) should have a header row with column names, followed by data rows. Each data row will create one slide in the final presentation.

Example

name title email department
John Doe Software Engineer john@example.com Engineering
Jane Smith Product Manager jane@example.com Product

Column Headers

The first row of your Excel file should contain column headers. These headers become the placeholder names in your PowerPoint template.

  • Header: name → Use {{name}} in template
  • Header: email_address → Use {{email_address}} in template
  • Header: First Name → Use {{First Name}} in template (spaces are preserved)

Excel-Style Addressing

In addition to column headers, you can address Excel data using Excel-style expressions:

Cell References

  • {{xlsx.Sheet1!A1}} - References cell A1 in Sheet1
  • {{xlsx.Sheet2!C5}} - References cell C5 in Sheet2

Named Ranges

  • {{xlsx.Sheet1!namedRange}} - References a named range in Sheet1
  • Use Excel's Name Manager (Ctrl+F3) to view and create named ranges

Excel Tables

  • {{xlsx.Sheet1!Table1}} - References an Excel table named "Table1" in Sheet1
  • Excel tables must be formatted as tables (Ctrl+T) and given a name
  • Tables are useful for populating PowerPoint tables and charts

Examples

  • Single cell: {{xlsx.Sheet1!A1}} for a KPI value
  • Named range: {{xlsx.Sheet1!ChartTitle}} for a chart title
  • Table: {{xlsx.Sheet1!SalesData}} for a data table

Multiple Sheets

If your Excel file contains multiple sheets, you can reference data from any sheet using the xlsx.SheetName! prefix. The active sheet (the one open when you save) is used by default for basic column header addressing.

Data Types

Excel cells can contain:

  • Text: Any text value
  • Numbers: Numeric values (will be converted to text)
  • Dates: Date values (format may vary)
  • Formulas: Formulas are evaluated and the result is used
  • Images: Images embedded in Excel cells can be used in presentations (insert images into cells, then reference them in your template)

Best Practices

1. Clear Headers

Use clear, descriptive column names:

  • ✅ Good: employee_name, start_date, department
  • ❌ Avoid: col1, data, field1

2. Consistent Data

Keep data consistent within columns:

  • Use the same format for dates
  • Use consistent naming conventions
  • Avoid mixing data types in the same column

3. No Empty Rows

Avoid empty rows in your data range. Empty rows will still create slides (with empty placeholders).

4. Special Characters

  • Column headers with spaces are supported: {{First Name}}
  • Avoid special characters that might cause issues: !@#$%^&*()

File Requirements

  • Format: .xlsx (Excel 2007+ format)
  • Maximum file size: Check service limits
  • Encoding: UTF-8 for text data
  • Supported: Excel formulas, formatting (basic)

Tips

  1. Test with Sample Data: Create a small test file with 2-3 rows to verify your template works correctly.

  2. Clean Your Data: Remove any formatting that might interfere (merged cells, complex formulas).

  3. Column Order: Column order doesn't matter - reference columns by their header names.

  4. Large Files: For very large Excel files, consider splitting into smaller files for faster processing.

  5. Excel Tables: Format your data as Excel tables (Ctrl+T) and name them for easier referencing in templates.

  6. Active Sheet: Remember that the active sheet (the one open when you save) is used by default for column header addressing.

  7. Named Ranges: Use named ranges for frequently referenced values like chart titles or KPIs.

Troubleshooting

  • Headers Not Recognized: Ensure the first row contains your column headers
  • Empty Slides: Check for empty rows in your data
  • Missing Data: Empty cells will result in empty placeholders
