What are the limits of Data Quality Profiler?
Types are inferred from observed nonempty cells, not certified schemas. Leading-zero identifiers remain text. Numeric summaries ignore nonnumeric cells and use sample standard deviation and interpolated quartiles. Missing tokens are explicit. 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.
