Formulas topic

excel_plus has a built-in formula engine: sheet.evaluate(cell) computes one cell and excel.recalculate() recomputes the whole workbook. Anything not built in can be added with excel.formula.registerFunction. This page lists what is supported.

Engine

• Operators: + - * / ^ %, comparisons (= <> < <= > >=), &, unary minus
• References: relative & absolute (A1, $A$1) and ranges (A1:B10)
• Cross-sheet references (Sheet2!A1)
• Defined names / named ranges
• Array broadcasting (A1:A5>2)
• Shared-formula expansion on read
• Error values (#DIV/0!, #N/A, #VALUE!, #REF!, #NAME?, #NUM!) and circular-reference detection (#CIRC)

Functions

Math: SUM · PRODUCT · ABS · INT · SQRT · POWER · MOD · SIGN · ROUND · ROUNDUP · ROUNDDOWN · TRUNC · CEILING · FLOOR · MROUND · LN · LOG10 · LOG · EXP · PI · SUMPRODUCT

Statistics: AVERAGE · COUNT · COUNTA · COUNTBLANK · MIN · MAX · MEDIAN · MODE · STDEV · STDEVP · VAR · VARP · PERCENTILE · QUARTILE · CORREL · LARGE · SMALL · RANK

Criteria: SUMIF · SUMIFS · COUNTIF · COUNTIFS · AVERAGEIF · AVERAGEIFS · MAXIFS · MINIFS (text criteria support */? wildcards)

Logical: IF · IFS · SWITCH · AND · OR · NOT · TRUE · FALSE · XOR · IFERROR · IFNA

Information: NA · ISERROR · ISERR · ISNA · ISNUMBER · ISTEXT · ISLOGICAL · ISBLANK · ISEVEN · ISODD

Text: CONCAT · CONCATENATE · TEXT · LEN · UPPER · LOWER · TRIM · LEFT · RIGHT · MID · PROPER · REPT · EXACT · SUBSTITUTE · REPLACE · FIND · SEARCH · VALUE · TEXTJOIN · CHAR · CODE · T

Lookup & reference: MATCH · INDEX · VLOOKUP · HLOOKUP · LOOKUP · XLOOKUP · CHOOSE · OFFSET · INDIRECT · ROW · COLUMN · ROWS · COLUMNS

Financial: PMT · FV · PV · NPER · NPV · IRR · RATE

Date & time: DATE · TIME · TODAY · NOW · YEAR · MONTH · DAY · HOUR · MINUTE · SECOND · WEEKDAY · DAYS · DATEDIF · EDATE · EOMONTH

Dynamic arrays: FILTER · SORT · UNIQUE · SEQUENCE

Dynamic-array functions compose inside other functions (e.g. SUM(UNIQUE(A1:A100))) but do not yet spill across the grid; a top-level dynamic-array formula returns its first cell.

Not yet supported

• Array-formula spilling (writing a result across multiple cells)
• Long-tail statistical / engineering / database functions
• R1C1-style INDIRECT (only A1-style text is resolved)
