TXT text files are one of the most basic and commonly used formats. Whether it is system files, data storage or note records, we will update the contents of many TXT files. When it is necessary to update the name of the product or modify the contact information, we will manually open each text file for search and replacement. The efficiency is the lowest file, and it is also very easy to miss and make mistakes, especially in the face of hundreds or even thousands, such repeated labor will cause most people to stop here. So how should we update and replace the words and numbers in the text in the shortest possible time?
Here, I 'd like to explain to you a few things from self-contained systems to practical small tools. In many ways, it is easy to realize batch replacement, making TXT text work easier. Come and try it with me!
When do you want to batch modify a keyword in a TXT file to another keyword?
File content needs to be updated
the keywords in TXT text files are not suitable for further use, so it is necessary to replace the old keywords with new texts in batches, such as the original identification, number and name. Continued use of the old keywords will lead to inaccurate content. Through batch replacement, all the old keys in TXT files can be replaced at one time, and no more line-by-line search is required, which is more efficient.
Easy system identification
when importing TXT files, the system will identify the data according to the keywords. If the keywords are still old, the system cannot find the corresponding fields, and problems such as identification failure or content dislocation may eventually occur. Therefore, when updating the key fields, some keywords of TXT must be replaced with new contents so that the system can correctly understand and work smoothly without getting stuck and reporting errors.
Reduce the risk of labor
if batch replacement is not possible, only one text can be manually modified one by one. It is a waste of time not to say that problems such as omission, error correction and format destruction will haunt us. When the frequency of keyword occurrence increases, manual modification is difficult to be completely accurate. Batch replacement can make all files use a set of new keywords, greatly reducing human errors and improving the overall quality.
