Convert Single-Quote Delimited Data

Use single quotes instead of double quotes for field quoting. Learn when single-quote delimiting is appropriate and how to configure it.

Quoting Rules

Detailed Explanation

Single-Quote Delimited Data

While RFC 4180 specifies double quotes as the standard quoting character for CSV, some systems and tools use single quotes instead. The TSV/CSV converter supports both quote styles through the Quote Character option.

Example: Single-Quoted CSV Input

Name,Description,Category
'Widget, Standard','A basic widget',Hardware
'Gadget, Pro','The ''premium'' gadget',Electronics
'Cable','6'' extension',Accessories

Converted to TSV (with single quotes)

Name	Description	Category
Widget, Standard	A basic widget	Hardware
Gadget, Pro	The 'premium' gadget	Electronics
Cable	6' extension	Accessories

When to Use Single Quotes

Single-quote delimited files are commonly found in:

  1. SQL exports: Some database tools export CSV with single quotes to match SQL string literal syntax
  2. Programming contexts: Languages like Python and JavaScript use single quotes for strings
  3. Legacy systems: Older mainframe and ERP systems sometimes use non-standard quoting
  4. Mixed-content data: When data frequently contains double quotes but rarely contains single quotes

Escaping With Single Quotes

The escaping rule is the same regardless of quote character: the quote character is doubled to represent a literal occurrence within a quoted field. With single quotes, '' represents a literal single quote.

Switching Between Quote Styles

You can use this tool to convert between quote styles by:

  1. Loading data with the original quote style selected
  2. Changing the quote character option
  3. The output will use the new quote style with proper escaping

Use Case

Working with data from SQL database exports, legacy systems, or tools that use single-quote quoting conventions, and converting them to standard double-quoted CSV for broader compatibility.
