When the List Randomizer 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
My table lost its columns.
This tool shuffles whole lines - paste rows that belong together as single lines to keep them paired.
Two lines look identical after shuffling.
Duplicates are kept as they are - run the list through our list deduplicator first if you need them removed.
The new order keeps coming out similar.
Short lists have few possible orders - add more items or shuffle again for a fresh arrangement.
Blank lines appear in the output.
Empty lines count as items - remove them from the paste before you shuffle.
I need the original order back.
Keep a copy of the pasted list before shuffling, since the tool does not store any history.
I want the same shuffle next time.
Copy the shuffled result out of the page - rerunning creates a brand new arrangement each time.
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:
- Shuffling lines that hold comma separated fields
- Editing a line after shuffling
- Judging fairness from two short shuffles
- Pasting the list with blank rows
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
Does shuffling change the line contents?
No - only the order of the lines changes, and every character within a line stays as you pasted it.
Can it handle long lists?
Yes - paste as many lines as you need and the whole list is reordered in one pass.
Is the order different each time?
Yes - each shuffle deals the lines freshly, so running it again gives another arrangement.
Is my list uploaded?
No - the shuffle runs in your browser and nothing is sent anywhere.
