Convert PNG to NDJSON

PNG (Portable Network Graphics) is a widely-used raster image format that supports lossless data compression.

Key features of PNG files include:

• Lossless compression, maintaining image quality
• Support for transparency and alpha channels
• Wide color depth support (up to 48-bit true color)
• Excellent for images with text, logos, or sharp edges

When used for data extraction, PNG files can contain:

• Screenshots of data tables or spreadsheets
• Graphs, charts, or other data visualizations
• Scanned documents or receipts

Common use cases for PNG image data extraction:

• Digitizing printed or handwritten data
• Extracting information from charts and graphs
• Converting visual data representations into editable formats
• Automating data entry from image-based sources

By converting PNG images containing data to formats like CSV or Excel, you can transform visual information into structured, analyzable data for further processing or integration into various data analysis tools.

NDJSON (Newline Delimited JSON) is a convenient format for storing or streaming structured data that may be processed one record at a time. Each line in an NDJSON file is a valid JSON object, separated by a newline character.

This format is particularly useful for handling large datasets, as it allows for easy parsing and processing of data line by line without loading the entire file into memory.

Key Features

• Each line is a self-contained JSON object
• Simple to read and write sequentially
• Ideal for streaming and logging applications
• Supports partial processing of large datasets

NDJSON is commonly used in data pipelines, log processing, and scenarios where you need to append new data to existing files without modifying the entire structure.
