Methods

Signature	Description
`EnsureSeekable(stream: std::vector<uint8_t>)` → `std::vector<uint8_t>`	Ensures the byte buffer is seekable (identity for in-memory data).
`GetEntry(archive: ZipArchive, uri: std::string_view)` → `ZipArchiveEntry`	Gets a ZIP entry by URI, normalizing leading slashes and backslashes.
`LoadDocument(entry: ZipArchiveEntry)` → `XmlDocument`	Loads an XML document from a ZIP entry.
`LoadRelationships(archive: ZipArchive, relationshipsUri: std::string_view, sourceUri: std::string_view)` → `std::unordered_map<std::string, std::string>`	Loads relationships from a .rels file in the archive.
`FindRelationshipTarget(workbookRelationships: std::unordered_map<std::string, std::string>, expectedPath: std::string_view)` → `std::string`	Finds the first relationship target whose resolved path matches expectedPath.
`FindRelationshipTargetByType(workbookRelationships: std::unordered_map<std::string, std::string>, relationshipType: std::string_view)` → `std::string`	Finds the first relationship target whose inferred kind matches relationshipType.
`LoadSharedStrings(archive: ZipArchive, workbookRelationships: std::unordered_map<std::string, std::string>, options: LoadOptions, diagnostics: LoadDiagnostics)` → `std::vector<std::string>`	Loads the shared strings table from the archive.
`LoadDateStyleIndexes(archive: ZipArchive, workbookRelationships: std::unordered_map<std::string, std::string>, options: LoadOptions, diagnostics: LoadDiagnostics)` → `std::unordered_set<int>`	Loads the set of cell-format indexes that use a date number format.
`ParseBoolAttribute(attribute: XmlAttribute)` → `bool`	Parses a boolean attribute (“1” or “true” yields true).
`ParseIntAttribute(attribute: XmlAttribute)` → `std::optional<int>`	Parses an integer attribute, returning empty on failure or null attribute.
`ParseDoubleAttribute(attribute: XmlAttribute)` → `std::optional<double>`	Parses a double attribute, returning empty on failure or null attribute.
`NormalizeFormula(value: std::string_view)` → `std::string`	Normalizes a formula string by trimming and stripping a leading ‘=’.
`ReadInlineString(inlineStringElement: XmlElement)` → `std::string`	Reads the concatenated text from an inline-string element.
`TryParseNumber(rawValue: std::string_view, numberValue: CellValue)` → `bool`	Attempts to parse a raw string as a number (int or double).
`AddIssue(diagnostics: LoadDiagnostics, options: LoadOptions, issue: LoadIssue)`	Records a load issue and notifies the warning callback if present.
`ResolveWorksheetUri(sheetIndex: int, relationshipId: std::string_view, workbookRelationships: std::unordered_map<std::string, std::string>, archive: ZipArchive, diagnostics: LoadDiagnostics, sheetName: std::string_view, options: LoadOptions)` → `std::string`	Resolves the worksheet part URI from a relationship id, falling back to convention.
`ResolvePartUri(sourceUri: std::string_view, target: std::string_view)` → `std::string`	Resolves a relative or absolute target against a source URI.
`RelationshipPointsTo(candidate: std::string_view, expectedUri: std::string_view)` → `bool`	Tests whether a candidate path matches an expected URI (case-insensitive).
`GetRelationshipTargetKind(candidate: std::string_view)` → `std::string`	Infers the relationship type from a resolved target path.
`LooksLikeDateFormat(formatCode: std::string_view)` → `bool`	Tests whether a number format code looks like a date/time format.
