Can trimming whitespace fix part number mismatches between vendor files and my master SKU list?

Yes, if the mismatch is caused by leading or trailing spaces. If a vendor exports 'SKU-4821 ' with a trailing space, trimming normalizes it to 'SKU-4821' so it matches your master list correctly.

Will quantities, weights, or pricing data be affected?

No. The tool only modifies text-type cells by trimming whitespace. All numeric values are preserved exactly as provided by the vendor.

Does this work on files with multiple sheets — like one tab per warehouse location?

Yes. Every worksheet in the workbook is cleaned in one pass, with tab names and their order preserved in the output.

Can I process multiple vendor files at once?

Yes — you can upload multiple files and each is cleaned independently, returning one cleaned workbook per vendor file.

Does the tool work on .xls files from older vendor systems?

Yes. Both .xlsx and .xls files are accepted as input. The output is always returned as an .xlsx file, so if your downstream system requires .xls specifically, you would need to convert after cleaning.

Clean Vendor Inventory and Shipment Excel Files Before They Enter Your System

Vendor-provided inventory sheets and carrier shipment exports are among the least standardized files in any supply chain workflow. Blank rows between product categories, empty columns between fields, and part numbers or SKUs padded with spaces cause lookup failures and import errors the moment these files touch your WMS, ERP, or tracking system. Deliteful's Excel Clean tool strips the structural inconsistencies before the file enters your workflow.

Logistics coordinators routinely receive Excel files from multiple vendors, each with their own informal formatting conventions. A single vendor inventory sheet might use blank rows to separate product families, leave columns blank between weight and dimension fields, and export part numbers as text with trailing spaces — meaning your VLOOKUP against the master SKU list returns N/A even though the part number looks identical on screen. Multiplied across 10 vendors and weekly updates, this is a significant source of data entry errors and reprocessing time.

Deliteful removes every fully empty row and column and trims whitespace from all text cells across every worksheet in the workbook. Quantities, weights, prices, and dates are never touched. Sheet names and order are preserved. The cleaned file is structurally consistent and ready to match against your master data, import into your WMS, or pass to a 3PL portal without manual intervention.
