What are the limits of Categorical Data Encoder?
Fit categories from training input only, or apply a saved mapping to another dataset. Lexical category ordering is explicit, not semantic. Unknown values can error or map to all-zero / -1. Missing values are treated as an explicit category. Outputs preserve source columns and add encoded fields; maximum 50 categories per column and 64 total columns. 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.
