THE LITTLE DETAILS
Need a quick answer before you start? Here’s how it works.
No. Parsing, cleaning, previews, reports, CSV export, and ZIP creation all run in your browser. Your CSV contents never leave this tab.
Yes. Every value is treated as text. CSV files do not carry column types, so when reopening in Excel, import SKU and ZIP columns as Text to keep their zeros.
You choose the date column, exact input format, and output format. We never infer date formats. Invalid dates stay unchanged and are listed in the report.
Three successfully imported files in total on this browser, up to 500 data rows per file. The trial does not reset daily. The header is excluded; blank data rows count toward the limit. The built-in sample is free to try.
Save a named recipe in your browser, then apply it to files with the same column headers in the same order. Recipes contain rules and header names, never data rows.
Cells and headers beginning with =, +, -, or @, including after whitespace, receive an apostrophe on export to prevent formula execution. This intentionally changes those exported values. Always review sensitive data before sharing.
LESS FUSS. BETTER FILES.
