About the usage and precautions of the vlookup function. In any case, an error occurs, indicating that there is no deep understanding of the connotation and extension of the vlookup function, that is to say, the function has not been really mastered. Today, I will briefly summarize the reasons and precautions for the wrong use of vlookup. I hope you can truly master the king of functions - Vlookup!
1. Data type problem. First, check whether the data type of the target column to be applied is the same as the data type of the target column to be applied. If one is text and the other is a number, the result must be an error, and neither one can match.
2, the space problem. It is necessary to check whether there are spaces before and after the value of the target cell to be applied, especially when the excel data table is exported from the system.
3. Whether the target application column is located in the first column; this cannot be repeated, this is the most significant feature of the vlookup function;
4. Is the third parameter correct? That is, the object to be applied is the first column to be displayed, which is also the basic meaning of the vlookup function;
5. Make it clear whether the second parameter is an absolute reference or a relative reference.
6. Whether there are merged cells in the data table . If so, restore it.
7. Pay attention to exact search or fuzzy matching.
