Preview: data_dump_v1.csvWrong delimiter detected
Found semicolons in the data rows while the header expects commas.
Duplicate headers
Column "name" appears twice. ImportFix can safely rename both.
Problem
CSV imports fail for boring reasons
Most failed imports are not complicated. They usually come down to file structure problems like broken row lengths, wrong delimiters, duplicate headers, encoding issues, blank rows, or malformed quoting. ImportFix is built to catch those problems fast and clean them up before you upload to another system.
Wrong delimiter
Exports from older tools often use semicolons or tabs instead of commas.
Inconsistent row lengths
A single missing cell is enough to shift every field after it.
Duplicate headers
Import mapping breaks quickly when the same header appears twice.
Blank rows and columns
Whitespace, blanks, and line ending noise add up fast in real exports.
Leading and trailing whitespace
Quoted fields often break when systems escape text differently.
Mixed line endings
Encoding mess usually shows up as bad headers or unreadable names.
Broken quoting
Duplicate records create subtle import mistakes, not obvious failures.
Encoding-related mess
Small structural issues are usually what stop an otherwise valid file.
