## **Data Requirements**

### **All 8 Currencies Required (in any order):**
- USD, EUR, GBP, JPY, AUD, CAD, CHF, NZD

### **Value Ranges:**
- **CPI Actual:** Any realistic percentage (e.g., 1.0 - 5.0%)
- **PMI:** 0-100 scale (50 = neutral, >50 = expanding, <50 = contracting)
- **Use decimal format:** `3.45`, not `3.45%`

### **Important:**
- No merge cells or complex formatting
- Column headers needed (any name with "CPI", "PMI", "Currency" is recognized)
- Empty cells or 0 values = not imported

---

## **Generate Template Files**

Run this command to create example files:

```bash
python create_excel_template.py
```

This creates:
- `example_monthly_data.xlsx` (multi-sheet)
- `example_monthly_data_single_sheet.xlsx` (single sheet)
- `example_monthly_data.csv` (CSV format)

---

## **AI Prompt for Data Generation**

See [EXCEL_IMPORT_PROMPT.md](EXCEL_IMPORT_PROMPT.md) for ready-to-use prompt templates.

### **Quick Prompt:**
```
Generate realistic monthly economic data for the 8 major currencies 
for June 2026 in Excel format:

CPI: Actual inflation rates (YoY %)
PMI: Composite PMI readings (0-100 scale, 50=neutral)

Currencies: USD, EUR, GBP, JPY, AUD, CAD, CHF, NZD

Provide in two sheets:
- Sheet 1: CPI (Currency, Target %, Actual CPI %)
- Sheet 2: PMI (Currency, Composite PMI)
```

---

## **Troubleshooting**

| Problem | Solution |
|---------|----------|
| "Import Error: Sheet not found" | Use correct sheet names: "CPI" and "PMI" |
| "No data imported" | Check column names contain "Currency", "CPI", "PMI" |
| "0 values not imported" | Use non-zero values; 0 = skip |
| "File locked" | Close Excel before importing |
| "Column mismatch" | Ensure 8 currencies (USD, EUR, GBP, JPY, AUD, CAD, CHF, NZD) |

---

## **Workflow Example**

1. **Ask AI:**
   ```
   Create an Excel file with CPI and PMI data for the 8 major 
   currencies for June 2026. Make it realistic based on current 
   economic trends.
   ```

2. **Download** the Excel file from AI

3. **Open APEX Layer 1** → Monthly Entry tab

4. **Click Import Excel** → Select the file

5. **Data auto-fills** the entry form

6. **Click Save & Calculate Scores** → Done!

7. **Check Dashboard** tab for the generated signal

## **Notes**

- App auto-detects file format (Excel or CSV)
- If Excel has both formats, app tries multi-sheet first
- PMI default is 50 (neutral); enter actual PMI, not delta
- CPI target values are auto-looked up from config
- You can edit values after import before saving
