Data Analysis 15 - Summary of Excel Basic Technology in Office

0. Foreword:

  • This part of the summary is to summarize the definition of each basic technology. After understanding the name and definition of the basic technology, it is convenient to search and learn related technologies. The notes will not explain all the operations in detail, but will explain the names and functions of the basic operations, which can be retrieved by yourself.
  • This article has the following effects for most readers
    • 1. You can retrieve some commonly used operation names in excel
    • 2. Get the excel of office

1. Basic summary:

  • Why do you need to install excel in office, but not wps?
    • Because excel is an important tool in data analysis, wps lacks some professional functions, or most people prefer white P, and WPS looks like white P, but actually pays, excel seems to pay, but after cracking, it can perfectly white P all Function.
    • Installation information:
      Link: https://pan.baidu.com/s/1vE7-EGl-J1dmP2yiqzj4Nw
      Extraction code: 1234
  • Protection settings:
    • 1. Protect workbook: encrypt the entire excel file
    • 2. Protect the structure of the workbook: you cannot operate excel, you can only view it
    • 3. Protect the worksheet: encrypt the worksheet
    • 4. Protect cells: encrypt some cells
    • 5. Data types in excel: text, numbers (dates are special numbers), logical values, error values
    • 6. Sometimes a formula is written in a cell, but it does not run after pressing Enter. The reason may be that the cell format is set to text format.

2. Fast filling:

  • Understand the concept of the fill handle: the small cross in the lower right corner of the cell (for the content to be filled, the effect of pressing ctrl and not pressing ctrl is different)
  • Selective filling: Mastering this filling method is equivalent to mastering all filling methods
    • Select a cell, place the mouse on the lower right corner, wait until it turns into a fill handle, then right-click, wait until the fill handle turns into a mouse, and then pull down to select the fill.

3. Common error values:

  • #VALUE: text (non-text numbers) and numeric operations
  • #DIV/0! : The denominator in division is 0
  • #NAME! : wrong formula name
  • #N/A: lookup value does not exist

4. Common operations:

  • When the cell number exceeds 12 digits, it will be expressed in scientific notation, and a single quotation mark can be added in front of the number when inputting to display the original number.
  • Text number × 1: convert the text number into a number, you can also choose the way of +0
  • alt+=: quick sum
  • ctrl+shift+direction: quickly select a continuous column or row, ctrl+direction (quickly move to the border), shift+direction (select a grid)

5. Positioning conditions: called by the F5 shortcut key, the purpose is to batch process cells of the same type

  • Through the positioning conditions, you can perform batch processing on a certain type of cells that need to be selected individually. It should be noted that if you are editing a batch of cells, you cannot simply enter, you need to use ctrl+Enter.

6. Unification of date data format

  • First of all, the date format should be processed into the form in excel, and then the text data can be converted into a unified date format by using the value function or the method of ×1.
  • For the processing of text data, you can use the text function, so that you can change the irregular text date into the form in excel, and finally ×1 into date data.

7. Freeze pane: Freeze the first row or column or multiple rows and multiple columns. When sliding the slider, the frozen part will always be displayed, which is convenient for data comparison.


8. Paste Special > Skip Empty Cells: When pasting, only the part with content will be pasted, and the part with empty value will not be pasted. In this way, the data in the part with empty value will not be modified when it is pasted into the data of the same result.


9. Data verification:

  • The first method: use a bunch of data as a drop-down list
  • The second method: Circle the invalid data (the premise is to set the value range of the corresponding area in the data verification, if it exceeds the range, it will be circled)

10. Quick fill: Ctrl+E

  • You can enter content in the first cell of a certain column, as an example, then select this cell, hold down Ctrl+E, and this column will be filled according to the example you gave.
  • Here, quick filling is understood as a built-in smart application of excel, which can fill the corresponding content without formulas.

11. Split into columns: separate the data in the same column according to certain rules, and this operation is in the data operation column.


12. Transpose: Change row to column or column to row, this operation can be realized by paste special.


13. Combined calculation:

  • Merge data in the same format but located in different worksheets. For example, the data of all branches can be summarized through the merge operation, provided that the data format of all branches is the same. This operation is in the data operation column.
  • Note that combined calculations not only include summation but also many other operations

14. Conditional formatting:

  • Format cells according to conditions, this operation is in the start action bar.
  • Among them, there are many ways to create rules in the new rules, and the way to create rules through formulas can dynamically change the format of the corresponding cells.

15. Cell references

  • A certain cell needs to be referenced in the formula, and it is necessary to distinguish between absolute references and relative references when referencing here
  • Absolute reference: Whether filling by row or by column, the cell content is locked and unchanged
  • Relative reference: fill row auto-increment by row, fill column auto-increment by column

16. Operators in excel formulas

17. Excel formula related

  • First of all, you must master the operator, and note that parentheses are supported in operations
  • In the formula operation bar, you can set the tracking cell reference, so as to know which other cells are used in the formula of the corresponding cell to participate in the operation.
  • The error checking in the formula action bar can help you quickly locate the cells with formula errors one by one.
  • The formula evaluation in the formula operation bar allows you to clearly see the calculation results of each step of the complex formula.

18. Common functions

  • Statistics and logic classes: maximum (MAX), minimum (MIN), summation (SUM), numerical counting (COUNT), counting (COUNTA), averaging (AVERAGE), conditional counting (COUNTIFS), conditional summation ( SUMIFS), conditional average (AVERAGES), frequency statistics (FREQUENCY), ranking (RANK), judgment (IF), and (AND), or (OR), not (NOT).
  • Mathematics: rounding (INT), remainder (MOD), rounding (ROUND), absolute value (ABS), arithmetic square root (SQRT), random number generation (RANDBETWEEN)
  • Text type: get substring (MID), text length (LEN), number to text (TEXT), text repetition (REPT), replace specified position text (REPLACE)
  • Date class: year (YEAR), month (MONTH), day (DAY), current date (TODAY), current date and time (NOW), date of the month before and after the specified date (EDATE), the last day of a certain month serial number (EOMONTH), calculate date difference (DATEDIF)
  • Search and reference types: vertical search (VLOOKUP), offset (OFFSET), return serial number by search content (MATCH), search content by row and column number (INDEX), cell reference specified by text (INDIRECT), reference row data (ROW) , reference column data (COLUMN), horizontal lookup (HLOOKUP)

19. Array formula

  • Array: a collection of cells or values ​​(understood as multiple values ​​forming the smallest unit of calculation)
  • Array formula: A formula that takes an array as a parameter. A formula performs multiple input operations and may return multiple result values
  • Call array formula: After writing the formula, use ctrl+shift+enter
  • Note that the calculation result of the array is a unified area, if you want to delete it, you must delete it all
  • Example:

20. Pivot table

  • This part of the content is the method of selectively viewing the existing data
