SQL Timesaver – Add comma separators

add comma separators to SQL cover image

This one-minute SQL timesaver showcases a free online comma separator tool, designed to simplify the process of adding comma separators to your SQL code. is a Free Comma Separating Tool that separates one or more characters and text strings using delimiters such as commas (,), semicolon (;), quotes (\”, ‘), braces ({}), pipes (|), or slashes (/ \\ ) .

It’s an online tool that can be used to simplify delimiting tasks, including text, email, zip codes, clauses, keywords, and more.

The tool can handle SQL, program code, and plain text.

You can simply enter your non-delimited data on the left, select a delimiter & hit convert to get separated data on the right.

More configurations are available if the defaults aren’t what you need!

Step by Step Guide

In this example we use Big Query, copying the field names from the screen, then pasting them into the online tool

Our video breaks it down into three animated steps

Step 1 – Copy the text to the clipboard

Here we show a Google BigQuery public dataset being used. Unlike SQL Server where you can easily select ‘columns’ from a table and pick which ones you need

Drag and Drop Field Names in SQL (SSMS)

Google BigQuery does not have the same feature, so using a delimiter tool can save us lots of time

We simply select the column headers from the output and click ctrl+C to copy them to the clipboard

Step 2. Go to the website

and paste the copied data into the box on the left hand side of the screen paste fields on the left

Step 3.  Hit the Chevron to add the comma separators

This then processes the data and provides a formatted comma separated output, which we then copy and paste into our SQL editor

The column names are copied into the tool and the output is a nicely formatted list of those field names all neatly separated with a comma


You can now paste this straight into your query editor

The tool is not limited to commas either, it can be customised to provide other delimiters too, spaces, new lines and semi colons

This is a very useful tool to add comma separators to SQL, but its usefulness doesn’t stop there, it can be used in programming, or any other use you can think of

We have no affiliation to the site or the site owner, but we do use the tool sometimes and we find it useful. there are other such tools available on line, but this is our go to choice to help save time

If you use Google BigQuery it can be very useful
