rendlio diagnose

Analyse a workbook and report what a conversion would do — never writes documents, never exposes cell contents.

rendlio diagnose <input> [options]

Arguments

Argument	Value	Required	Meaning
<input>	FILE	yes	Path to a .xlsx / .xlsm file, or - for stdin.

Options

Option	Value	Default	Env var	Milestone	Meaning
--report	PATH|-	—	—	M1	Writes the compatibility report JSON (- = stderr summary only). Without it, diagnose prints the human summary and writes no file.
--culture	BCP-47	en-US	RENDLIO_CULTURE	M1	Locale for separators and month names when a number format lacks an explicit [$-LCID].

Examples

Print the human summary; write nothing.

Diagnose-mode reports additionally record rendered entries, so you see everything detected, not only the deviations. They are safe to share — static text plus counts and locations, never cell contents.
