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.

FAQ
Common questions
What is ImportFix?
A pre-import CSV repair tool for fixing structural issues before upload.
Is this a spreadsheet editor?
No. It is focused on diagnosing and repairing import-related CSV problems.
Do I need an account?
No, not for the MVP.
What file types does ImportFix support?
ImportFix supports CSV files and standard Excel workbook uploads (.xlsx and .xls). Excel files are converted from the first worksheet into the same repair flow before preview and export.
What are the free limits?
Free export is intended for files up to 1,000 rows or 500 KB. Larger files and some advanced repair options trigger premium export.
Does my file stay private?
For standard files, processing is designed to happen in the browser where possible. That means you can inspect and repair local CSVs or Excel uploads without needing an account.
Can it fix every broken CSV?
No. It should handle common structural problems well, and clearly show what it found when a file needs manual review.
Can I preview the repaired file before exporting?
Yes. ImportFix is built around scanning the file, applying selected repairs, and showing the repaired preview before download.
Does ImportFix support Excel files?
Yes. ImportFix can read standard Excel workbooks for input and convert the first worksheet into the repair workflow. You can export cleaned CSV, and premium users can export repaired data as an Excel .xlsx workbook.
Who is this for?
Admins, operations people, consultants, developers, and small businesses dealing with messy CSV exports.
