🔄 PRN to CSV Converter

This Python script batch-processes binary .PRN files and converts them into clean .CSV files for easier analysis.

🚀 Features

• Reads binary .PRN files containing 32-bit floating-point values.
• Drops initial 29 records (often metadata or calibration noise).
• Outputs clean CSV files with a single Spectrum column.
• Processes all .PRN files in a specified input directory.

📁 Folder Structure

inputprnswc/       # Put your .PRN files here  
outputcsvswc/      # CSVs will be saved here after conversion

🛠️ How It Works

1. Reads binary data in 4-byte chunks (single float per chunk).
2. Converts values into a list of dictionaries.
3. Skips the first 29 entries.
4. Writes the rest into a .csv using pandas.

✅ Usage

Just update the paths and run:

input_folder = r"inputprnswc"
output_folder = r"outputcsvswc"
process_all_prn_files(input_folder, output_folder)
