Totals do not perform currency conversion, accounting classification or financial certification. Up to 1,000,000 characters, 10,000 data records, 100 columns and 100,000 cells across the sources. Files for multi-source tools are limited to 4,000,000 bytes total. Reports retain at most 500 diagnostic findings and state any omitted count. CSV and JSON outputs are limited to 4,000,000 characters. Output is budgeted incrementally before retaining each row; expanded decimal output counts toward the same 4,000,000-character limit even when input uses short exponent notation.",
