JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It's commonly used for web APIs, configuration files, and data storage due to its simplicity and compatibility with most programming languages.

How does PNG to JSON conversion work?

The tool uses optical character recognition (OCR) technology to identify and extract text and data from PNG images. It analyzes the image structure to detect tables, rows, and columns, then organizes the extracted data into JSON format with proper structure.

What types of images work best?

Images with clear, high-resolution text and well-defined table structures work best. Screenshots of spreadsheets, scanned tables with good contrast, and images with clear borders between cells produce the most accurate results.

Will the extraction be 100% accurate?

While the tool uses advanced OCR technology, extraction accuracy depends on image quality, text clarity, and table complexity. Always review the extracted JSON and make corrections if needed. Complex layouts or poor image quality may reduce accuracy.

Can I extract data from charts?

Yes, the tool can extract data from charts and graphs in PNG images. However, accuracy depends on the chart type and clarity. Simple bar charts and line charts with clear labels work better than complex visualizations.

Yes! All image processing happens directly in your browser using JavaScript. Your PNG images are never uploaded to any server, ensuring complete privacy and security for your sensitive data. The entire extraction process takes place locally on your device.

What if the extraction is inaccurate?

If the extraction is inaccurate, try using a higher resolution image, improve the contrast, or ensure the table structure is clear. You can also manually edit the JSON file after extraction to correct any errors.
