What are the limits of Data Value Mapper?
Dictionary has from/to columns or your selected source/target names. Duplicate normalized source keys are rejected. Matching can trim whitespace and ignore case; original unrecognized values can be retained, blanked or rejected. This is a value lookup, not a multi-table row join. Inputs stay in browser memory. No workbook is created. Table limits: 5 MB total text, 25,000 rows, 64 columns and 200,000 cells; expensive operations have stricter limits. Processing can be cancelled.
