A simple GUI application that converts Excel/CSV files containing subtitle data into SRT format.

• Supports both Excel (.xls, .xlsx) and CSV files
• Simple graphical user interface
• Handles Japanese subtitle data
• Automatic time and duration calculations

• Python 3.6 or higher
• PyQt5
• Required Python packages (listed in requirements.txt)

1. Clone or download this repository
2. Create a virtual environment (recommended):

python -m venv venv
source venv/bin/activate  # On Windows, use: venv\Scripts\activate

3. Install the required packages:

pip install -r requirements.txt

1. Run the script:

python srt.py

2. In the application window:
   • Click "Browse" to select your Excel/CSV file
   • Click "Convert" to start the conversion
   • The converted SRT file will be saved in the same directory as the input file

The Excel/CSV file must contain the following columns:

• ページナンバー (Page Number)
• 送出タイミング (Timing)
• Duration
• 字幕文字列 (Subtitle Text)

The application will display error messages if:

• Required columns are missing
• Input file format is invalid
• Time format is incorrect

You can create a standalone executable for this application using PyInstaller:

1. Install PyInstaller:

   pip install pyinstaller

2. Run PyInstaller to generate the executable. You have two options:

   • Single file (--onefile):

     pyinstaller --onefile --windowed srt.py

     • The --onefile flag creates a single executable file.
     • The --windowed flag prevents a terminal window from opening (for GUI apps).
     • Pros: Easy to distribute, just one file.
     • Cons: Startup/loading time can be slower, as everything is unpacked to a temporary folder at runtime.

   • Directory (--onedir, default):

     pyinstaller --onedir --windowed srt.py

     • The --onedir flag (default) creates a folder containing the executable and all dependencies.
     • Pros: Faster startup/loading time.
     • Cons: Distribution requires sending the whole folder, not just a single file.

3. The executable or folder will be located in the dist directory.

4. Distribute the executable file (dist/srt.exe on Windows, dist/srt on macOS/Linux) or the entire folder (for --onedir) to users. They do not need Python installed to run it.
