ImportCheck vs Excel
Manual validation in Excel feels thorough — but it misses errors, takes hours and produces no audit trail. Here's what the two approaches actually deliver.
ImportCheck scans every row, every column, against every ERP rule — in under 30 seconds. No formulas. No guesswork. No missed errors.

Manual review misses what you don't know to look for
Excel review relies entirely on the analyst knowing which checks to run. Duplicate SKU detection requires a COUNTIF formula. VAT rate validation requires a data validation rule. Encoding issues are invisible.
ImportCheck runs a fixed, comprehensive set of ERP-specific rules on every file — no formula setup, no knowledge gaps, no missed checks.
The result: zero silent errors reaching your ERP, regardless of who runs the validation.
Based on common ERP catalog error types: missing headers, duplicate SKUs, invalid prices, wrong VAT rates, encoding issues, parse errors.
Hours of manual review vs. 30 seconds
The time difference grows with file size. At 5,000 rows, manual Excel validation is not feasible without statistical sampling — which means errors get through.
| File size | 📊 Excel (manual) | IC ImportCheck |
|---|---|---|
| 100 rows | 15–30 min | < 5 seconds |
| 500 rows | 1–2 hours | < 10 seconds |
| 2,000 rows | 4–8 hours | < 20 seconds |
| 10,000 rows | Not feasible | < 30 seconds |
| 100,000 rows | Not feasible | < 2 minutes (Pro) |
Manual validation doesn't scale — automated validation does
Catalog size grows. Team turnover happens. Manual validation quality degrades. ImportCheck applies the same rules every time.
👤
Individual knowledge
Excel
Depends on which team member does the review. Rules are in someone's head — or a shared doc nobody updates.
ImportCheck
Rules are defined once in the engine and applied identically to every file, regardless of who uploads it.
📈
Growing file sizes
Excel
Reviewing 500 rows is feasible. 5,000 rows is impractical. 50,000 rows is impossible without sampling.
ImportCheck
Scales linearly. Up to 100,000 rows validated in under 2 minutes on the Pro plan.
🔁
Repeated validation cycles
Excel
Each re-check of a corrected file requires the same manual effort. Teams get fatigued and start skipping checks.
ImportCheck
Re-validation is instant. Re-upload, click validate, done. The same checks run every time.
The errors Excel misses — and ImportCheck catches
Some catalog errors are obvious. Most are invisible to a manual reviewer.
Wrong CSV separator
📊 Excel
Excel silently merges all columns into one when the separator doesn't match its locale setting — the file looks "open" but the data is completely wrong.
IC ImportCheck
Auto-detects separator. Raises PARSE_ERROR immediately if the structure is ambiguous.
Encoding mismatch (latin-1 / UTF-8)
📊 Excel
Accented characters appear garbled. Easy to overlook, especially in large files with few accented names.
IC ImportCheck
Detects encoding automatically. Preserves all characters correctly regardless of the source tool.
Duplicate SKU on row 3,847
📊 Excel
Requires a COUNTIF formula across the entire SKU column. Easy to forget. Easy to miss if the formula isn't applied to every row.
IC ImportCheck
Cross-row duplicate check runs automatically on every analysis. Every duplicate is flagged with both row numbers.
VAT rate 15% (not authorised)
📊 Excel
No built-in ERP rule set. The reviewer needs to know which rates are valid and manually check every cell.
IC ImportCheck
INVALID_VAT error raised for any value not in the authorised set: 0, 2.1, 5.5, 10, 20.
Negative stock on row 612
📊 Excel
Easy to miss in a 1,000-row file. Conditional formatting helps, but only if the reviewer sets it up correctly.
IC ImportCheck
INVALID_STOCK error raised for every negative or non-integer stock value.
Price with comma decimal (49,90)
📊 Excel
Excel auto-converts comma decimals in its locale — hiding the format issue. The ERP importer may not.
IC ImportCheck
PRICE_FORMAT warning raised. The value is still validated — and the ERP risk is flagged explicitly.
Time saved, errors prevented, imports that succeed first time
Switching from manual Excel validation to ImportCheck pays back within the first prevented failed import.

Frequently asked questions
Can't I just use Excel formulas to validate my catalog?
You can — but you need to build and maintain the validation formulas yourself, know which ERP rules to encode, apply them to every new file, and manually compile the results into a shareable report. One missed formula means errors slip through. ImportCheck does all of this automatically, consistently, on every file.
ImportCheck generates an Excel report — why not just use Excel from the start?
The report format is Excel because it's universally readable and shareable. The validation engine itself runs structured, ERP-specific rules that go far beyond what a typical Excel user would set up manually. The report is the output — the validation logic is what you can't replicate easily in a spreadsheet.
What if I only have small catalogs — is ImportCheck still worth it?
Yes. Even 100-row catalogs contain errors. Manual review of a 100-row file takes 15–30 minutes, requires domain knowledge of ERP rules and produces no shareable output. ImportCheck validates the same file in under 5 seconds and generates a report you can send to your supplier.
How is ImportCheck different from the ERP's built-in import checker?
ERP importers stop at the first error and give you a generic message. They require you to be inside the ERP, often in a staging environment. ImportCheck runs outside the ERP, requires no credentials, reports every error at once, and produces a structured report — before you ever touch the import tool.
Does ImportCheck replace my ERP integration workflow?
No. ImportCheck is a pre-import validation step that sits before your existing workflow. You still use your ERP importer as normal — but you arrive at that step with a clean, validated file instead of discovering errors mid-import.
