- you have a list of emails from Excel and you want to paste it into the mailing system,
- you have a column of identifiers and you need to prepare an SQL query with the clause

How to use the data separation tool - step by step
- Paste data into the left text box
Copy your list from a spreadsheet, text file, email or report and paste it into the left text box. These can be values on separate lines or separated by another separator. - Configure separator and operation mode
Select:- separator type (default comma
,), - whether values should be on one line or divided into multiple lines,
- whether you want to remove duplicates and empty entries.
- separator type (default comma
- Run conversion
Click a conversion button (e.g. "Separate with commas" or "Convert"). The tool will analyze the entered data, apply the selected separator, remove blank lines and - if you want - eliminate duplicates. - Copy the result from the right field
After a while, a ready list will appear in the right text field. You can:- copy it to the clipboard,
- paste it into a CRM system, mailing tool, SQL query, CSV file or script,
- save the resulting text in a notebook or spreadsheet.
Paste the list on the left, select a separator and click conversion. On the right, you will immediately get the data in a format ready to use in SQL, CSV or any other system.
Advanced configuration options - full control over the
format For more demanding users, the tool offers a number of options that help perfectly match the result to the requirements of a specific system or file format.
Selection of separators
The default separator is a comma, but you can also choose:
- semicolon
;- often used in CSV in Europe, - tab - convenient when working with TSV files,
- space, vertical bar
|or any custom character, - combinations like
"value", tailored to specific APIs.
Quotation marks and value formatting
Many systems require that each value be surrounded by quotation marks. The tool can automatically:
- add quotation marks around each value (e.g.
"[email protected]"), - remove unnecessary spaces before and after separators,
- normalize the notation, e.g. force lowercase or trim whitespace.
Remove blank lines and duplicates
Data from sheets or reports often contains blank lines or repeated values. Built-in filters allow you to:
- remove all empty entries (blank lines, zero characters),
- remove duplicates, leaving only unique values,
- preserve or ignore case differences when comparing.
Single-line or multi-line mode
Depending on your needs, you can:
- combine everything into one line (e.g. for SQL:
1,2,3,4), - keep the line division with a different separator inside,
- create "columns" to import in a spreadsheet or BI tools.
