impl Function for TextSplitFn

Splits text into a dynamic 2D array by column and optional row delimiters.

TEXTSPLIT supports multiple delimiters, optional case-insensitive matching, and output padding.

Remarks

• Column delimiter is required; row delimiter is optional.
• match_mode=0 is case-sensitive, match_mode=1 is case-insensitive.
• ignore_empty=TRUE drops empty segments created by adjacent delimiters.
• Rows are padded to equal width using pad_with (default #N/A).

Examples

title: "Split CSV row"
formula: '=TEXTSPLIT("A,B,C", ",")'
expected: "{A,B,C}"

title: "Row and column split with padding"
formula: '=TEXTSPLIT("A,B;C", ",", ";")'
expected: "{A,B;C,#N/A}"

    a: "Yes by default; set match_mode to 1 for case-insensitive delimiter matching."

fn caps(&self) -> FnCaps

Capability flags for this function

fn name(&self) -> &'static str

fn min_args(&self) -> usize

fn arg_schema(&self) -> &'static [ArgSchema]

fn eval<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], ctx: &dyn FunctionContext<'b>, ) -> Result<CalcValue<'b>, ExcelError>

The unified evaluation path.

fn namespace(&self) -> &'static str

fn variadic(&self) -> bool

fn volatile(&self) -> bool

fn aliases(&self) -> &'static [&'static str]

Optional list of additional alias names (case-insensitive) that should resolve to this function. Default: empty slice. Implementors can override to expose legacy names. Returned slice must have ’static lifetime (typically a static array reference).

fn function_salt(&self) -> u64

fn eval_reference<'a, 'b, 'c>( &self, _args: &'c [ArgumentHandle<'a, 'b>], _ctx: &dyn FunctionContext<'b>, ) -> Option<Result<ReferenceType, ExcelError>>

Optional reference result path. Only called by the interpreter/engine when the callsite expects a reference (e.g., range combinators, by-ref argument positions, or spill sources).

fn dispatch<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], ctx: &dyn FunctionContext<'b>, ) -> Result<CalcValue<'b>, ExcelError>

Dispatch to the unified evaluation path with automatic argument validation.
