High-Density Syntax Cheatsheet

Immediate, atomic structural reference rulesets for enterprise-level calculation mapping.

🎯 Advanced Vector Matching

Modern Matrix Match =XLOOKUP(val, look_arr, ret_arr)

Index Intersect Coordinates =INDEX(matrix, row, col)

Relative Array Location =MATCH(val, lookup_arr, 0)

Multi-Criteria Summation =SUMIFS(sum_rng, crit_rng1, crit1, ...)

Multi-Criteria Average =AVERAGEIFS(avg_rng, crit_rng1, crit1, ...)

Filtered Element Count =COUNTIFS(crit_rng1, crit1, ...)

Scoped Variables Block =LET(var1, val1, calculation)

Anonymous Custom Function =LAMBDA([param1], calculation)

Array Parameter Processing =MAP(array, LAMBDA(x, calc))
