Excel: three steps to get a two-dimensional tables turn one-dimensional table

Note: This article was operational tool Excel 365

 

Introduction omitted two-dimensional table with one-dimensional table, directly to the question, how will excel table into a two-dimensional one-dimensional table?

 

Original two-dimensional table ▼

 

 

 

In data management, typically using one-dimensional table processing and analysis (on this point can understand simple database, data is stored using a database for data management), the original Chinese style classic two-dimensional table to be transformed into one-dimensional table below by step 3 the two-dimensional table into one-dimensional table, look at the data processing one-dimensional table obtained:

 

Processing one-dimensional table obtained ▼

 

 

 

 

Ideas ▼

 

The original two-dimensional table has multiple rows title / header and column header / header, the actual work may exist in more complex cases, consider all the row headers merger , all of the column headings merge , into a simple two dimension tables , the use of reverse flow of the PivotTable, treated two-dimensional table Unpivot , becomes only three (two attributes, a value) of the one-dimensional table, and then the two data split column process, It becomes one-dimensional table, then the data is simply to give the final data .

 

 

 

Tools ▼

 

Use powerquery for conversion into two-dimensional table of one-dimensional table, detailed steps are as follows

 

STEP 01▼

Click Data> from table / area, loading data into powerquery , uncheck the "table contains the title," the data is loaded into powerquery

 

 

 

STEP 02▼

在powerquery操作界面，对列1、列2进行合并列操作，合并为1列，选中第1列及第2列（原行头），点击转换>合并列

 

注：此处需添加分隔符，以便后续进行拆分

 

 

 

STEP 03▼

合并列后，进行行列转置，点击转换>转置

 

 

 

注：转置后若存在列值为空，可点击转换>填充>向下进行向下填充，适用于列标题（头）为合并单元格的情况

 

 

 

STEP 04▼

转置后将第一行用作标题，点击转化>将第一行用作标题

 

 

 

 

STEP 05▼

进行第二次合并列，选中第1列及第2列（原列头），点击转化>合并列，数据变为简单的二维表

 

注：此处需添加分隔符，以便后续进行拆分

 

 

 

STEP 06▼

对处理后的二维表进行逆透视，选中第1列数据，点击转化>逆透视列>逆透视其他列，数据变为仅有3列的一维表

 

 

 

STEP 07▼

对于仅有3列的一维表，进行拆分列反向操作，将之前合并的值拆分掉

 

注：由于合并列后部门值重复，作为标题的“供应商-产品”中存在部分值后面有后缀（_1）的情况，可通过powerquery中的拆分列或excel中的查找替换进行处理

 

 

 

STEP 08▼

点击“关闭并上载”保存数据，可在excel中查看到处理得到的数据

 

 

 

STEP 09▼

最后一步，将数据的表头进行更改，稍作处理变为最终想要得到的数据

 

注：数据中存在在powerquery中加上了后缀（_1）的值，需要进行处理

 

 

以上，为二维表转一维表的简单操作，还有很多别的处理办法，欢迎大家分享。
