Group List
Turn a flat list into rows, tuples, or chunks while keeping the original order and choosing the exact output format.
A QUICK WALKTHROUGH
How to use this tool
- Paste a list up to 100,000 characters and choose its literal input separator.
- Choose the number of items per group, output separators, wrappers, and final-group padding.
- Group the list, review the exact result, then copy it or download a text file.
Fixed-size chunks in input order
Group size means the maximum number of items in each output group. The tool walks from the first item to the last without sorting. The final group remains shorter unless you enable padding, which appends the chosen padding value until that group reaches the selected size.
Literal input and exact output formatting
Choose newline, comma, tab, semicolon, or one to 20 literal custom characters for input. Item and group separators have the same presets plus optional empty custom output. Add up to 20 characters before and after every group. No regular expression is executed. Input is limited to 50,000 parsed items and output to 500,000 characters.
GOOD TO KNOW
Common questions
Does group size mean the number of groups?
No. It is the maximum number of items placed in each group. The number of groups is calculated from the item count.
What happens to an incomplete final group?
It stays shorter by default. Enable padding to fill its missing positions with the padding value.
Are spaces or empty items changed?
Items are preserved exactly unless you enable trimming or removal of empty items. A custom separator is always literal text, not a regular expression.
