Question 1

How do I split a specific column from tab-separated text?

Accepted Answer

Select the 'Split columns' tab, paste your tab-separated text, make sure the delimiter is set to Tab, enter the column index you want (1-based), and the output will show only that column's values.

Question 2

Can I extract all columns at once?

Accepted Answer

Yes. Check the 'Extract all columns' checkbox in Split mode. The output will show each column separated by a visual divider, so you can see all columns side by side.

Question 3

How does Combine mode work?

Accepted Answer

In Combine mode, paste values into separate column textareas. The tool merges them line by line using the separator you specify. For example, two columns with 3 rows each produce 3 combined rows.

Question 4

What delimiters are supported?

Accepted Answer

The preset buttons cover Tab, Comma, Semicolon, Pipe, and Space. You can also type any custom delimiter in the text input — including multi-character separators or escape sequences like 	 for tab.

Question 5

Can I use this tool to process CSV files?

Accepted Answer

Yes. For CSV data, set the delimiter to Comma. The tool will split or combine lines based on commas. For CSV files with quoted fields, use a proper CSV tool, as this splitter uses simple string splitting.
