What are the limits of Data Dictionary Builder?
One dictionary entry per observed column. Inferred storage/type examples are suggestions. Supply optional metadata as JSON keyed by exact column names, with description, unit, owner and allowed fields. Outputs Markdown documentation and a CSV dictionary; never an invented glossary. 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.
