With this program, you can easily concatenate multiple text files into one file. Reference steps:
Click the "Import Files" area or drag files directly to this area to select TXT, CSV or other text files. You can select multiple files at once, even dozens or hundreds of files.
In the file list, you can use the sort buttons to adjust the file order to ensure they are concatenated in the order you want.
Click the "Download Merged File" button, and the system will automatically process and download the merged file with all files concatenated binary-wise into one file.
📱 When you need to merge file contents on computer or mobile devices, use this program to quickly complete the task. The program can merge and connect binary data of TXT, CSV and other text files. Multiple files, dozens or hundreds of files can be quickly concatenated.
🌟 The program can be used on computers and mobile devices. Regardless of whether your device is Windows, Mac, Linux, Android or iOS, you can use it by simply opening a browser.
What File Formats Does the File Concatenation Tool Support?
The program supports the following file formats:
📄 .txt - Plain text files
📊 .csv - Comma-separated values files
📝 Many commonly used text file formats: .log .js .text .md .xml .html .css etc.
⚠️ Note: Each file should use the same encoding to avoid garbled text in the merged file due to different encodings. For example, concatenating files encoded in GB2312 with files encoded in Big5 will cause garbled text when viewing the merged file.
🔄 This tool supports batch detection of multiple file encodings and also supports converting file encodings. After converting all files to UTF-8, concatenating file contents can solve the garbled text issue.
❓ Why does concatenating file contents easily cause garbled text?
Different encodings assign different code numbers to each character. After merging, if one encoding is used to decode the file content, it will cause decoding errors and garbled text. For example, imagine English speakers and French speakers chatting together, but if the translator forcibly translates all sounds according to French pronunciation, translation errors will occur. Similarly, directly concatenating binaries of files with different encodings will cause similar phenomena - multiple files with different character encodings will result in a new file that displays garbled text and character recognition errors when opened.
