Do you often encounter situations where you copy and paste a piece of text from a web page to Notepad and end up with a bunch of extra spaces in front of each line? Or export text files with a messy format that requires manual removal of the front white space line by line? This kind of problem seems small, but it is really annoying to do, especially when you have dozens or hundreds of text files to deal. Today, let's talk about how to efficiently delete the blank at the beginning of each line and see what useful tools are available on the market.

Deleting the blank space at the beginning of each line can quickly unify the code format, facilitate team collaboration and version management, and improve development efficiency.
2. Data log cleaning and analysis scenario. Each line of the system-exported log file begins with a timestamp and has spaces. After the spaces at the beginning of each line are cleared, the data can be directly imported into the analysis tool to avoid parsing errors caused by format problems and ensure the accuracy of analysis.
3, academic literature citation collation scene. When copying document content from a PDF, each paragraph often begins with a space. Deleting the first space of txt line can quickly standardize the citation format, meet the typesetting requirements of academic papers, and save manual adjustment time.
4. Network content acquisition and processing scenario. Web pages crawled by crawlers often contain irregular indent spaces. Deleting the blanks at the beginning of each row can quickly purify data, facilitate subsequent content analysis and database storage, and improve the efficiency of data processing.
5. Document standardization filing scenario. The format of text reports submitted by different departments of the enterprise varies. The unified deletion of spaces at the beginning of each line can establish a standardized document library, facilitate retrieval and management, and enhance the standardization of enterprise knowledge management system.
