Output Formats

Array Mode

Rows become array items with named fields:

data:
  - # Row 1

    department: Engineering
  - # Row 2
    name: Jane Smith
    age: 25
    department: Design

Object Mode

Rows become keyed objects:

data:
  row_1:
    name: John Doe
    age: 30
    department: Engineering
  row_2:
    name: Jane Smith
    age: 25
    department: Design

Advantages of TSV Format

Tab-separated values (TSV) offer several advantages over other formats:

Data Integrity

• Natural delimiter
• Rare in text content
• Less escaping needed
• Clear field separation

Compatibility

• Unix-friendly format
• Easy processing
• Widespread support
• Simple structure

Performance

• Fast parsing
• Efficient storage
• Quick processing
• Easy validation

Frequently Asked Questions

What's the difference between array and object mode?

Array mode creates a list structure where each row becomes an array item with named fields. Object mode creates a keyed structure where each row becomes a named object. Array mode is better for ordered data, while object mode is better when you need to reference specific rows.

How does type detection work?

When enabled, the converter automatically identifies and converts data types. Numbers remain unquoted, true/false become boolean values, and array-like strings are converted to proper YAML arrays. This ensures your data maintains its proper types in the YAML output.

How are special characters handled?

Special characters are automatically escaped when needed to ensure valid YAML output. Values containing YAML-special characters are properly quoted, and multi-line content is formatted correctly while preserving its structure.

Is my data secure?

Yes, all processing happens entirely in your browser. No data is sent to any server, ensuring your TSV data remains private and secure throughout the conversion process.
