When the CSV Delimiter Changer 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
Columns split wrongly after conversion
Values contain the new delimiter - quote those fields or pick a delimiter that does not appear in the data.
It does not detect my current delimiter
Set the source delimiter manually; mixed files need to be normalised first.
Quotes disappeared
Re-quote on conversion; fields that still contain the separator must stay quoted.
The file opens with everything in one column
The app expects a different separator - convert to what that app documents.
Tab conversion produced stray characters
Use real tab characters, not the literal text "\t".
Line endings changed
Line endings are preserved; if the target needs different ones, fix that in the editor after conversion.
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:
- Changing the delimiter without checking values that contain it
- Assuming the current delimiter without inspecting the file
- Breaking quoted fields during manual edits
- Ignoring locale settings that re-split on open
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
Which delimiters can I switch between?
Comma, semicolon, tab, pipe and any single custom character you specify.
Does it fix values that contain commas?
Quoted fields are handled correctly - they keep working when the separator changes.
Can it handle semicolon files from European Excel?
Yes - that is one of the most common conversions this tool performs.
Is my file uploaded?
No - the conversion happens entirely in your browser.
