Capability SummaryLENB can be inserted from the function dialog or typed directly in a worksheet cell to count text length by bytes.Microsoft explains that LenB returns the number of bytes used to represent a string, especially for double-byte character scenarios.Google Sheets supports formulas and function help while editing, but the cited page does not specifically document LENB.Notion formulas support text-length logic such as length(), mainly for database properties rather than spreadsheet cells.Adobe Acrobat supports calculation fields in PDF forms, which is different from spreadsheet text functions such as LENB.
WPS AdvantagesAdvantage: LENB is available in a familiar spreadsheet workflow with both dialog-based insertion and direct formula entry.Compared with WPS: the cited Microsoft page focuses on LenB behavior in Microsoft environments.Compared with WPS: Google documents formula entry and help prompts, but this page is broader and not LENB-specific.Compared with WPS: Notion is better aligned with database property formulas than worksheet-style function entry.Compared with WPS: Adobe focuses on PDF form calculations instead of spreadsheet text-length functions.
