Poorly formatted spreadsheets lead to confusion, miscalculations, and missed opportunities. Conversely, clean formatting:

Formatting Data in Excel: 6 Essential Techniques

1. Master Basic Formatting Tools

Font Styles & Colors: Use bold headers, italics for notes, and red/green to flag priorities.
Cell Borders: Define table boundaries with Alt + H + B shortcuts.
Alignment: Center titles, right-align numbers, and use Wrap Text for long entries.

Pro Tip: Use Format Painter (Ctrl + Shift + C/V) to copy styles instantly.

2. Conditional Formatting: Automate Insights
Highlight critical data automatically:

Color Scales: Visualize sales performance (green = high, red = low).
Data Bars: Compare values at a glance.
Custom Rules: Flag duplicates, deadlines, or outliers.

=AND(A2 > 100, A2 < 200)

3. Custom Number Formats
Tailor how data displays without altering values:

Dates: Convert 20230825 to 25-Aug-2023 with dd-mmm-yyyy.
Currency: Add symbols and decimal precision ($1,250.00).
Phone Numbers: Format 1234567890 as (123) 456-7890 using "(###) ###-####".

4. Table Formatting for Dynamic Data
Convert ranges into tables (Ctrl + T):

Auto-expand formulas and filters.
Add banded rows for readability.
Enable sorting and slicers for dashboards.

5. Clean Data with Text Functions

TRIM: Remove extra spaces: =TRIM(A2)
PROPER: Capitalize names: =PROPER("john doe") → “John Doe”
TEXT: Convert numbers to readable formats: =TEXT(B2, "$#,##0.00")

6. Use Styles and Themes Consistently
Apply predefined Cell Styles for headers, totals, or warnings. Save custom themes to maintain branding across files.
