2b:null 2c:["$","title",null,{"children":"Google gTTS with Excel and VBA | Christophe Yamahata | Observable"}] 31:T56f,# Google gTTS with Excel and VBA *This notebook introduces macro-enabled Excel XLSM files that demonstrate how to integrate **Google’s gTTS** (Google Text-to-Speech) functionality with Excel using VBA. The solution allows for easy text to speech conversion, either with or without the use of the Python library.* #### Option 1: No Python Simply download the XLSM file [gTTS_no_python.xlsm]
This option uses VBA macros to connect directly with Google’s TTS API (via the URL https://translate.google.com/), eliminating the need for Python. #### Option 2: With Python Download the XLSM file [gTTS_with_python.xlsm] and Python script [gTTS.py].
This option utilizes Google’s gTTS library in Python to convert text to speech and play the audio using pygame. The script is triggered from the XLSM file via a VBA macro. 32:T49f,## Files You can download the files directly from the ᥫ **Files Pane**: #### Option 1: No Python 🐍 XLSM file: gTTS_no_python.xlsm (macro-enabled Excel file) #### Option 2: With Python 🐍 * Python script: gTTS.py * XLSM file: gTTS_with_python.xlsm (macro-enabled Excel file) For Option 2, make sure to keep both files in the same folder. Once downloaded, you must unblock the XLSM file before using it. To do so, right-click the file, select **Properties**, and check the box labelled **Unblock** at the bottom. Additionally, ensure that macros are enabled when prompted, as VBA is required for the tool’s functionality. 33:T691,gtts_python_script = ` """ This script converts text to speech using Google Text-to-Speech (gTTS) and plays the audio using pygame. ### Setup Instructions: 1.

You can test this script in Visual Studio Code, Command Prompt, or any other Python execution environment. 4.
