数据透视表: 快速汇总、分析、交叉表
图表可视化: 柱状图、折线图、饼图、组合图
数据清洗: 去重、填充、格式统一
宏自动化: VBA 宏录制和编写

常用公式模板

汇总统计

=SUMIF(A:A,">=2024-01-01",B:B)          -- 条件求和
=COUNTIF(B:B,">100")                      -- 条件计数
=AVERAGEIF(C:C,"北京",D:D)                -- 条件平均

查找引用

=VLOOKUP(E2,数据源!A:C,3,FALSE)          -- 垂直查找
=INDEX(B:B,MATCH(D2,A:A,0))              -- 反向查找
=XLOOKUP(查找值,查找列,返回列)             -- 现代查找

日期处理

=TEXT(A2,"YYYY-MM")                       -- 格式化日期
=EDATE(B2,3)                              -- 日期加减
=WEEKDAY(C2,2)                            -- 星期几

数据透视表技巧

拖拽字段到行/列/值/筛选区域
值汇总方式：求和、计数、平均值
值显示方式：百分比、累计
切片器：交互式筛选

使用示例

帮我写一个统计月度销售额的公式，需要按地区分类汇总

有一份客户数据表，有很多重复记录，帮我写清洗步骤

把这些数据做成可视化图表，展示季度对比趋势

VBA 常用宏

Sub 批量格式化()
    For Each cell In Selection
        If cell.Value > 100 Then
            cell.Interior.Color = RGB(255, 0, 0)
        End If
    Next
End Sub

适用场景

数据汇总报表
