在 VBA 中执行的工作表数据中最快的 VLOOKUP

Question

我正在寻找查找工作表数据中的值并在另一列中给出相应值的最快方法。查找必须在 VBA 内完成。仅执行 1 次查找（不再对同一数据集进行查找）。

例如，我们有这种形式的数据：

使用 VBA，在 B 列中找到与 A 列中的值 "key990000" 相对应的值的最快方法是什么？

Answer 1

我已经在排序和未排序数据、10 万行和 100 万行数据的上下文中测试了几个不同的函数。

最快的方法是使用 WorksheetFunction.Vlookup 或 WorksheetFunction.Index 和 WorksheetFunction.Match 的组合。但是如果要在同一列上进行 2 次或更多次搜索，那么最好将数据加载到数组中（这需要相对更多的时间）并循环遍历它（循环遍历加载的数组非常快）。

性能测试汇总结果（同时拥有10万行和100万行数据）

                | 100k rows   | 1m rows     |
---------------------------------------------
 Sub            | sort | uns  | sort | uns  |
---------------------------------------------
 WsF_vlookup    | 0.05 | 0.05 | 0.25 | 0.38 |
 WsF_idx_match  | 0.05 | 0.05 | 0.25 | 0.38 |
 loop_in_array  | 0.06 | 0.06 | 0.35 | 0.43 | - this is better for 2+ lookups
 range_find     | 0.10 | 0.12 | 0.80 | 0.95 |
 match_in_array | 0.11 | 0.11 | 0.65 | 0.80 |
 loop_in_sheet  | 0.14 | 0.16 | 1.2  | 1.39 |
 array_to_dict  | 0.5  | 0.65 | 61   | 87   |
 sheet_to_dict  | 1.5  | 1.70 | 75   | 100  |
