When the List Sorter seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
The numbers sorted as 1, 10, 2.
Switch to numeric mode - text sorting compares characters, so 10 reads before 2.
My header line moved to the bottom.
Headers have no value to sort on - pull the header out, sort the data, then paste it back on top.
Nothing changed when I sorted numerically.
Numeric mode reads the number at the start of each line - add or align the leading value so it can compare.
Lines with minus signs landed wrongly.
Use numeric mode, which understands negative and decimal values rather than their characters.
The order is backwards from what I wanted.
Flip the direction toggle to descending and sort once more.
I need the pre-sort order.
Keep a copy of the original paste - sorting replaces the order and the tool does not store history.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Sorting numbers as text
- Mixing headers into the data rows
- Sorting valueless lines numerically
- Losing the original order without a copy
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
What is the difference between numeric and alphabetical?
Numeric mode compares the number at the start of each line, while alphabetical compares the text character by character.
Can it sort in descending order?
Yes - choose descending and the largest or last value in your chosen mode comes first.
Will it remove duplicate lines?
No - this tool only reorders lines; use the list deduplicator to remove repeats.
Is my list stored?
No - sorting happens in your browser and the text is not saved.
