How to Indent Multiple Lines in VSCode
Indenting multiple lines in VSCode is the process of adding consistent whitespace to selected code blocks using keyboard shortcuts or editor commands.
You need this when formatting nested functions, aligning code structure, or fixing pasted snippets from external sources.
This guide covers 7 methods requiring 2-3 minutes total. Works on Windows, macOS, and Linux with any skill level.
Visual Studio Code handles bulk indentation better than most text editors. The Tab key does most of the work, but there are faster options depending on your situation.
Prerequisites
Before you start, confirm these requirements:
- Visual Studio Code version 1.80 or later installed
- Any operating system: Windows 10/11, macOS 10.15+, or Linux
- A file with multiple lines of code open in the editor
- No prior coding experience required
Time estimate: 2-3 minutes per method.
If you need to install VSCode on Ubuntu first, handle that before continuing.
Step One: How Do You Select Multiple Lines for Indentation?
Select lines by clicking at the start position, holding Shift, then clicking the end position. The editor highlights all text between both points, ready for indentation commands.
Action:
- Click at the beginning of the first line you want to indent
- Hold Shift and press the Down Arrow key repeatedly to extend selection
- Selected lines appear highlighted in blue (default theme)
Alternative method: Click and drag from start to end position.
For non-adjacent lines, hold Alt (Windows/Linux) or Option (macOS) and click each line. This creates multiple cursors for simultaneous editing.
Purpose: Selection defines which lines receive the indentation change. Without selection, only the current cursor line moves.
Step Two: How Do You Indent Selected Lines Using the Tab Key?
Press Tab with lines selected to shift all highlighted code right by one indentation level. The editor applies your configured tab size (default 4 spaces) uniformly across the selection.
Action:
- Select the lines using Shift + Arrow keys or click-drag
- Press Tab once
- All selected lines move right by one indent level
Press Tab multiple times for deeper nesting.
This keyboard shortcut works in JavaScript, Python, HTML, CSS, and every other language. The code block formatting stays consistent regardless of file type.
Purpose: Tab indentation is the fastest method for manual adjustments. Most developers use this daily for organizing nested structures and improving code readability.
Step Three: How Do You Outdent Multiple Lines?
Press Shift + Tab to move selected lines left by one indentation level. This reverses the Tab action and decreases the indent for highlighted code blocks.
Action:
- Select the over-indented lines
- Press Shift + Tab
- Lines shift left by one level (4 spaces or 1 tab by default)
Repeat for additional levels.
This shortcut handles unindent multiple lines situations quickly. Works identically on Windows, macOS, and Linux.
I use this constantly when refactoring code. Took me a while to build the muscle memory, but now it feels automatic.
Purpose: Outdenting fixes accidental over-indentation and restructures code during code refactoring sessions.
Step Four: How Do You Use Bracket Shortcuts for Indentation?
Press Ctrl + ] to indent or Ctrl + [ to outdent selected lines. These keyboard shortcuts offer single-level adjustments without the Tab key.
Action:
- Windows/Linux: Ctrl + ] (indent) or Ctrl + [ (outdent)
- macOS: Cmd + ] or Cmd + </strong>
- Result: Lines shift by one indentation level per keystroke
Some developers prefer this over Tab. Feels more deliberate, especially during [code review sessions.
Purpose: Useful when Tab key has conflicts with autocomplete or snippet triggers in certain language modes.
Step Five: How Do You Format Selection with a Command?
Press Ctrl + K, then Ctrl + F to apply language-aware formatting to selected code. The editor uses your configured formatter to fix spacing, indentation, and code alignment automatically.
Action:
- Select the code block to format
- Press Ctrl + K, release, then press Ctrl + F
- Alternative: Open Command Palette (Ctrl + Shift + P) and type “Format Selection”
The formatter applies rules based on file type. JavaScript gets different treatment than Python or HTML.
For consistent results, configure Prettier as your default formatter. It handles automatic indentation across most languages.
Purpose: Format Selection fixes multiple issues at once, not just indentation. Saves time when you need to format code in VSCode properly.
Step Six: How Do You Configure Automatic Indentation Settings?
Open Settings (Ctrl + ,), search for “Auto Indent”, and set it to Full. VSCode will automatically adjust indentation as you type and paste code.
Action:
- Press Ctrl + , to open Settings
- Search: Editor: Auto Indent
- Select Full from dropdown options (None, Keep, Brackets, Advanced, Full)
Full mode handles most scenarios. It analyzes code structure and applies appropriate indent levels automatically.
You can also edit settings directly. Learn how to open settings.json for manual configuration.
Purpose: Reduces manual indentation work significantly. Your editor preferences handle formatting while you focus on writing code.
Step Seven: How Do You Set Tab Size and Spaces Preference?
Configure tab width and spaces vs tabs in Settings to match your project’s coding standards. Most front-end projects use 2 spaces; Python typically uses 4.
Action:
- Open Settings: Ctrl + ,
- Search: Editor: Tab Size and set to 2 or 4
- Search: Editor: Insert Spaces and enable (checked = spaces, unchecked = tabs)
Check the Status Bar at the bottom. It shows current tab spacing configuration for the active file.
Click “Spaces: 4” or “Tab Size: 4” in the Status Bar for quick changes without opening Settings.
Purpose: Consistent indentation across your codebase prevents merge conflicts and improves readability during collaboration.
Verification
Confirm your indentation applied correctly:
- Visual check: Code blocks should align at the same level
- Enable Render Whitespace: Settings > Editor: Render Whitespace > All
- Dots appear for spaces, arrows for tabs
The minimap on the right side shows overall code structure. Inconsistent indentation appears as jagged edges.
Troubleshooting
Tab Key Inserts Character Instead of Indenting
Issue: Pressing Tab adds a tab character instead of indenting selected lines.
Solution: Select lines first before pressing Tab. Without selection, Tab inserts a character at cursor position.
Indentation Size Looks Inconsistent
Issue: Some lines have different spacing than others.
Solution: Disable “Editor: Detect Indentation” in Settings. This stops VSCode from overriding your preferences based on file content.
Format Selection Does Nothing
Issue: Ctrl + K, Ctrl + F produces no visible change.
Solution: Install a language-specific formatter extension. Default formatters may not exist for your file type. Set up autoformat with Prettier or ESLint for JavaScript projects.
Mixed Tabs and Spaces in File
Issue: File contains both tabs and spaces, causing alignment problems.
Solution: Open Command Palette (Ctrl + Shift + P), type “Convert Indentation”, select either “Convert Indentation to Spaces” or “Convert Indentation to Tabs”.
Alternative Methods Comparison
Choose the right method for your situation:
| Method | Speed | Best For | | — | — | — | | Tab / Shift+Tab | 1 second | Quick manual adjustments, small selections | | Ctrl+] / Ctrl+</strong> | 1 second | Users with Tab key conflicts, precise control | | <strong>Format Selection</strong> | 1-2 seconds | Language-aware formatting, multiple fixes at once | | <strong>Auto Indent (Full)</strong> | Automatic | Ongoing projects, reducing manual work |
Tab method handles 90% of daily needs. Format Selection works better for pasted code from external sources.
