All formatting properties are copied: bold, italic, underline, strikethrough, alignment, number format, and text overflow mode.

Horizontal Alignment

Use the Format menu or format bar to set text alignment:

Alignment	Description
Left	Text aligns to the left edge (default)
Center	Text is centered in the cell
Right	Text aligns to the right edge

Vertical Alignment

Alignment	Description

Number Formats

Cell Styles

Semantic cell styles apply a coordinated set of visual properties (background, text color, border, bold/italic) in one click. Access them from the Styles dropdown in the format bar, or via the Command Palette.

Style	Appearance	Use case
Normal	Clears style, restores defaults	Remove a previously applied style
Error	Red background, red text, red border	Highlight errors or invalid data
Warning	Amber background, amber text, amber border	Flag values that need attention
Success	Green background, green text, green border	Indicate passing/valid values
Input	Blue background, blue text, blue border	Mark cells for user input
Total	Subtle fill, bold text, top border	Summary/total rows
Note	Gray background, muted text, italic	Annotations and comments

Behavior:

• Applying a style clears any manual background and font color so the style colors take effect
• Applying “Normal” removes the style and restores default formatting
• Styles adapt to the current theme (light vs dark)
• When applied to a multi-cell range, borders appear only around the perimeter

Text Overflow

Control how text behaves when it’s wider than the cell:

Mode	Behavior
Clip	Text is cut off at the cell boundary (default)
Wrap	Text wraps to multiple lines within the cell
Spill	Text overflows into adjacent empty cells

Spill behavior:

• Spill stops at the next non-empty cell
• Spill stops at cells with visual formatting (bold, italic, etc.)
• Maximum spill is 8 cells

Access text overflow via the Cell Inspector (Ctrl+1).

Column Width

Action	Method
Resize column	Drag column border
Auto-fit column	Double-click column border
Auto-size column	Ctrl+0
