Text Join & Split Tool
Move between line-based and delimiter-separated text.
Output
How the text join & split tool works
Join lines with a delimiter or split delimited text onto separate lines.
Joining three lines with ', ' creates a comma-separated list without changing the item text.
Assumptions and limitations
The delimiter is treated as literal text, not a regular expression.
Inputs and results stay in your browser. Blank, invalid, or mathematically undefined inputs show a clean placeholder instead of a broken number.
Practical use
Use this text tool to explore scenarios quickly, then verify important decisions against the original source data or requirements.
Frequently asked questions
Does the text join & split tool send my data anywhere?
No. It runs client-side in your browser and makes no network requests.
Why is the result blank or shown as a dash?
One or more inputs are blank, outside the accepted range, or would make the calculation undefined. Check the labels and enter finite values.
Can I use decimal values?
Yes, where decimals are meaningful. Counts that represent whole items may require integers.
