Browser-local processing. No uploads, content logging, persistence or remote resource loading. Generated markup is inert text; files are treated as untrusted data.
Browser-local XLSX processing in a cancellable worker. No macros, formula evaluation, uploads or content telemetry. Formula expressions are preserved, but Code Station does not recalculate Excel formulas.
All source sheets retained; duplicate names receive deterministic suffixes. Unsupported workbook metadata is omitted.
