Review with confidence
1. Inspect a catalog
The public demo opens with five synthetic products. Anyone can choose a UTF-8 CSV at /review and privately review supplier or client catalogs before handover. The selected file, issue list and approvals stay in browser memory and are cleared by refresh. Map SKU and title, and optionally map price, description, image URL and variant group. Every column remains in its original order.
2. Approve exact changes
Whitespace trimming and embedded CRLF/CR to LF normalization require your approval. SKU trimming is never automatic. Duplicate SKUs, missing required values, invalid or ambiguous prices, and suspicious URLs require manual source review. We never delete duplicate rows, fetch remote images, or fill missing values.
3. Preview and export
Machine-import mode preserves approved cell values, including formula-like text. Spreadsheet-safe mode adds an apostrophe to dangerous formula prefixes, including headers, so those cells differ from the source. Every row stays in the preview. Complete corrected CSV and change-log downloads are free through 100 data rows; larger complete exports require Pro. Generic CSV only; no marketplace import compatibility is claimed.
Originals and the change log
Reset changes restores original cell values. CSV quoting and record separators are serialized consistently; exports are not byte-identical copies of the source. Change log row numbers are logical CSV record numbers with the header as row 1, not physical line numbers. Logs include the export mode and are themselves spreadsheet-safe: formula-like original values receive an apostrophe in the downloaded log.
Parsing and limits
The engine supports strict UTF-8 with optional BOM, comma, tab, and semicolon delimiters. Ambiguous delimiters require explicit selection; duplicate or blank headers and inconsistent record widths are rejected. Prices use a selected dot/comma decimal convention, accept up to two decimal places, and never use thousands grouping. A value such as 1,234 remains ambiguous. The limits are 10 MiB, 20,000 rows and 100 columns. Browser parsing runs in a dedicated worker and can be canceled. One bounded Chromium run covered the row and near-byte caps together plus the separate column cap; other browsers and devices still require owner acceptance.
