Inspect a CSV.
Without opening Excel.
Check the file before handing it off or importing it. Find uneven rows, duplicate headers and formula-like cells locally. Choosing a file here does not overwrite it.
Need to check an export without a spreadsheet converting its IDs? Start with Load example → Check CSV below. Try every check and export before deciding whether to pay $1 for continued use of this version.
1. Choose or paste a CSV
Select the delimiter yourself. An incorrect delimiter may make every row appear to have one column. This tool does not convert dates, prices or identifiers. A spreadsheet may still auto-convert values on import; choose text columns there to retain identifiers.
2. Review before exporting
| Record | Column | Finding | Explanation |
|---|---|---|---|
| Run a check to see results. | |||
Record numbers refer to CSV records, including the header. A quoted field can contain multiple physical lines. Only the first 200 findings are shown; the JSON report includes all findings and no original cell values.
Normalization preserves field strings, writes CRLF record endings and uses the chosen delimiter. Broken quoting is rejected, never guessed. Structural warnings are reported, not silently repaired.
A careful CSV handoff
- Keep the original export. Review a copy; do not overwrite your source file.
- Choose the actual delimiter and encoding. All values appearing in one column can mean the wrong delimiter, not a valid file.
- Check and review findings. These are structural checks and heuristics, not a certification that your destination will accept the file.
- If you need Excel next, import identifiers as Text. A normalized CSV is still plain text; it cannot force Excel's column types. See Microsoft's free instructions.
- Verify in the destination. Compare IDs, row counts and required columns against the original before an important import.
Will this recover lost zeros or fix Excel automatically?
No. It preserves the strings present in the input when exporting without optional formula prefixing, but it cannot reconstruct characters that were already lost. It does not control Excel, repair business rules or promise a successful import.
Why pay when free validators exist?
You may not need to. Free tools and Excel's import settings may already solve your problem. This $1 offer is for continued use of this small utility, with a pinned offline ZIP, source and reproducible checks. Evaluate the complete tool first; there is no subscription, activation server or custom support included.
