What is Vendor Catalog CSV Cleaner?
When the same vendor appears under multiple name variations and SKUs change format with every catalog update, ERP imports fail. PipeSheets standardizes vendor master data so your imports work the first time.
- Unified vendor identities: Entity resolution consolidates vendor name variations into canonical records for cleaner master data
- Standardized SKU format: Normalizes SKU patterns across suppliers to your internal convention
- Numeric values only: Strips currency symbols and normalizes decimal formats for ERP compatibility

How to Clean Supplier Master Data Before It Hits Your ERP
Supplier price list cleanup is not a one-time project. Every quarter a vendor sends a new catalog, and every catalog arrives in a slightly different shape - renamed headers, a new currency format, an extra summary row at the top. If you paste these straight into your ERP import template, every inconsistency flows into your vendor master data and stays there. The fix is a repeatable cleanup pass that runs before the file ever touches NetSuite, SAP, or Oracle.
The five problems hiding in almost every vendor catalog
Common vendor catalog problems, their causes, and fixes
| Problem | Why it happens | The fix |
|---|---|---|
| Same vendor under five different names | Each buyer types the name differently, and suppliers rebrand | Use the map values step to collapse known aliases (ACME CORPORATION, Acme Corp.) into one canonical spelling |
| Mixed SKU formats: ABC-123, abc_123, ABC123 | Every supplier follows their own convention | Find & replace with regex swaps separators, then a case transform forces uppercase - SKU normalization in two steps |
| Prices as $19.99, 19.99 USD, and 19,99 | Price lists come from different regions and systems | Find & replace strips currency symbols and text; a regex swap converts comma decimals to points |
| N/A, null, TBD, and blanks mixed together | Reps fill unknown values however they like | Standardize nulls converts every variant to a true empty cell so ERP validation behaves predictably |
| Headers like 'Unit Price ' or 'unit-price' | Manual edits and inconsistent Excel exports | Normalize headers to snake_case so every catalog maps to the same import template |
A repeatable workflow to clean supplier master data
Here is the pass procurement teams run in PipeSheets, start to finish:
Supplier catalog cleanup steps
- Upload the raw catalog (CSV or XLSX, up to 25MB on the free plan) and open the preview to see what you are actually dealing with.
- Run Quick Clean first. One click trims whitespace, standardizes null variants like N/A and NULL, removes fully empty rows and columns, and normalizes headers to snake_case.
- Add a map values step on the vendor name column to fold every known alias into one canonical name.
- Add find & replace steps for SKU normalization: a regex turns underscores into dashes, then a case transform uppercases the whole column.
- Strip pricing junk with find & replace - remove $ and USD, and swap comma decimals with a regex.
- Reorder columns to match your ERP import template exactly, and drop any columns the template does not use.
- Preview the result, download, and save the whole sequence as a pipeline named after the supplier. Next quarter's catalog takes one click.
One honest caveat: PipeSheets does not deduplicate rows. If the cleaned catalog still contains true duplicates - the same vendor and SKU on two rows - standardize everything in PipeSheets first, then run Excel's Remove Duplicates on the download. Deduplication only works after normalization anyway: Excel cannot tell that 'Acme Corp.' and 'ACME CORPORATION' are the same vendor until the names match exactly.
