⚙️ Step 1: Prepare Your Data

• Ensure your dataset is clean: no blank rows, merged cells, or inconsistent formats
• Organize data into structured columns with clear headers
• Save a backup of your original file before recording macros

📊 Step 2: Enable the Developer Tab in Excel

1. Go to File → Options → Customize Ribbon
2. Check Developer in the right pane
3. Click OK to enable the Developer tab

The Developer tab allows access to macro recording, VBA editor, and advanced automation tools.

🧩 Step 3: Record Your Macro

1. Click Developer → Record Macro
2. Give the macro a descriptive name (e.g., FormatLargeData)
3. Assign a shortcut key if desired
4. Choose where to store the macro (This Workbook or Personal Macro Workbook)
5. Perform the formatting steps manually:

• Apply bold headers
• Adjust column widths
• Set number formats
• Add borders or conditional formatting

1. Click Stop Recording when finished

🔧 Step 4: Run and Edit Macros

• To run a macro: Developer → Macros → Select Macro → Run
• For custom edits, open the VBA editor to tweak the script for:
• Applying formatting to specific ranges
• Automating tasks for multiple sheets
• Adding loops or conditional logic

Example VBA snippet:

Sub FormatLargeData()
    Dim ws As Worksheet
    For Each ws In ActiveWorkbook.Sheets
        ws.Cells.Font.Name = "Calibri"
        ws.Cells.Font.Size = 11
        ws.Rows(1).Font.Bold = True
        ws.Columns.AutoFit
        ws.Cells.Borders.LineStyle = xlContinuous
    Next ws
End Sub

This macro applies uniform formatting across all sheets in a workbook.

📈 Step 5: Integrate Macros with Excel Automation

• Combine macros with data imports to automatically format new datasets
• Use Power BI or Python for advanced analytics after formatting
• Automate report generation, chart creation, and summary tables
