Here are some ways to format PivotTable cells for a better presentation in Excel:

Number Formatting:

* Change Number Format: Right-click on a value field and select "Number Format" from the context menu. Choose a format that best represents your data (currency, percentages, decimals).
* Show/Hide Thousands Separators: Use this option within "Number Format" to improve readability for large numbers.

Conditional Formatting:

* Highlight Important Values: Apply conditional formatting rules to automatically highlight high/low values, differences from targets, etc. This can draw attention to key insights.

Font & Alignment:

* Adjust Font Size and Style: Change the font size and style for better readability. Consider using bold or italics for emphasis.
* Center Align Values: Centering value cells within the table can improve visual presentation.

Borders & Shading:

* Add Borders: Apply borders to separate rows, columns, or the entire table to enhance structure and clarity.
* Subtle Shading: Use light shading for alternating rows or headers to improve visual separation.

Grand Totals & Subtotals:

* Customize Grand Totals: Right-click the grand total cell and choose "Show Values" to display options like "Difference from previous period" or "Percentage of total."
* Format Subtotals: Format subtotals differently (bold, different font color) to distinguish them from regular data cells.

PivotTable Styles:

* Predefined Styles: Excel offers various built-in PivotTable styles that can change the overall look and feel with a single click.

Cell Margins:

* Adjust Cell Margins: Reduce or increase cell margins to control spacing and improve table compactness.

Remember:

* Maintain consistency: Apply formatting consistently throughout the PivotTable for a professional look.
* Avoid clutter: Don't overdo formatting. Keep it clear and focused on highlighting key information.

By implementing these formatting techniques, you can transform your PivotTables from basic data dumps to visually appealing and informative presentations.
