FAQ
Does the tool upload my CSV?
No. All parsing and conversions happen in your browser only.
What does “Validate” check?
It ensures every row has the same number of columns as the header.
How big can my file be?
It depends on your device memory, but a few megabytes works fine in modern browsers.
Why is my CSV failing validation?
Look for stray commas or quoted fields that were not closed—these break the column count.
Is quoting with double quotes supported?
Yes, the parser understands “","” escapes and double-quoted fields.
Can I undo or clear the form?
Click “Reset” in your browser or refresh the page; the tool stores nothing.
