How to Properly Escape Double Quotes in CSV Files?

Escaping Double Quotes in CSV Files

When dealing with CSV files, it is important to properly escape special characters to prevent errors during parsing. Double quotes, in particular, can be tricky to escape when they are used to express characters within a field.

Escaping Double Quotes for Inches

As demonstrated in the given example, a double quote next to a number can be interpreted as an inches symbol. To escape this, an additional double quote must be placed before the inches quote. For instance:

"Samsung U600 24""""","10000003409","1","10000003427"

Escaping Double Quotes for Field Closure

When a field is closed with a double quote, it is essential to escape the double quote itself. RFC-4180 specifies that a double quote appearing within a field must be escaped by another double quote. Therefore, the example should be written as:

"Samsung U600 24""","10000003409","1","10000003427"

Avoiding Backslashes

It is important to note that using a backslash to escape double quotes is not recommended. In the example provided, using a backslash resulted in the inclusion of a backslash character in the field name.

By properly escaping double quotes using additional double quotes, you can ensure accurate parsing and prevent potential errors when reading CSV files.
