What Is a List to Comma Separated String?
A list to comma comma-separated string means turning a list into one line. A comma separates each item. You can use this in coding, spreadsheets, or data tools.

For example:
Apple
Banana
Orange
Becomes:
Apple, Banana, Orange
This format is known as CSV (Comma Separated Values). It is common in web development and data work.

How the Tool Works
As a CSE engineer, I often use such tools in projects. The logic is simple.
- The user pastes a list in a box.
- The script removes extra spaces.
- The script joins all lines using commas.
- The output shows the final string.
Basic JavaScript Logic
The tool uses JavaScript. Here is what it does:
- Split the text by line using
\n
. - Trim each item to remove extra spaces.
- Remove empty lines.
- Join the clean items using
,
.
Input and Output
You paste a list into the input box. Then you click convert. You get the result in a new box. You can copy the result and use it anywhere.
Where You Can Use the Output
In Coding
Developers often need comma-separated strings. These go into arrays, JSON data, and SQL queries.
let fruits = ["Apple", "Banana", "Orange"];
In Excel
You may need to paste data into one cell in Excel. This format helps when working with long lists.
In CMS or Forms
Sometimes, content management systems need tags or values in one line. This format helps in such forms.
In Database Scripts
In SQL, you may write queries like:
SELECT * FROM products WHERE name IN ('Apple', 'Banana', 'Orange');
A comma-separated string helps build this kind of query.
