Source mapping / 02
Bring catalogs together.
Keep decisions visible where they are needed.
Two fictional files. One explicit mapping. Every record stays visible in the results.
01 / Columns
Map source fields
Choose which column in each file supplies a shared field. Values stay as text until validation.
Analyze your own CSV
Choose one local file (up to 2 MB) to replace the included example. It stays in this browser and is never uploaded.
Supports comma or semicolon CSV, UTF-8 with or without a BOM, quoted fields, and CRLF or LF line endings. Map all five fields explicitly after loading.

The initial selections explicitly map the sample files. You can change them and recalculate.

Platform-neutral CSV preview
The output includes every record, including conflicts and missing values. You can copy the text even if file downloads are unavailable.
Scope: Every parsed record is kept in either the cleaned or review download; rows with a field-count or quoting issue are flagged and include their source row and raw text when recoverable. A missing closing quote can cause the remainder of a file to become one review entry; recoverable raw text is retained. SKU conflicts are retained in review, never silently overwritten. Price accepts ASCII digits with an optional decimal point or comma and 1–2 decimal digits; stock accepts non-negative ASCII digits. EAN must be present and contain exactly 8 or 13 ASCII digits. We do not check an EAN checksum or GS1 assignment. Spreadsheet formula prefixes (=, +, -, @, tab, CR) are apostrophe-prefixed; a minus that looks like part of a number is treated as text too. This is general data mapping, not a platform-import guarantee.
