Your output, not a black box
The cleaned file and report appear here after processing.
- Identifiers stay text
- Leading zeros in SKUs are preserved.
- Duplicates stay visible
- Repeated rows are flagged, not silently deleted.
- No invented product facts
- No generated descriptions, prices or categories.
Review before importing. Formula-like values may receive a leading apostrophe for spreadsheet safety. Your shop may require different import formatting.
KNOW YOUR OUTPUT
Cleanup, not catalogue repair.
Whitespace is trimmed at the edges of headers and cells. Rows, field order and product content are preserved, except for reported spreadsheet-safety escapes. Output uses commas and UTF-8.
This does not validate prices, fill missing facts, merge duplicates or guarantee shop compatibility. Keep your original file and review the report before importing.
Server processed: your file is sent to KORPO for in-memory processing. The application does not save input or output files. Do not upload personal, sensitive or confidential data. Read the privacy details.
