Question 1

What types of tables can this tool accurately convert?

Accepted Answer

The PNG to Excel Converter works best with clear, grid-based tables such as invoices, reports, price lists, schedules, and scanned spreadsheets. It can also extract structured data from tables with merged cells, multi-line text, and simple headers, as long as the table boundaries and text are readable. For best accuracy, use images with strong contrast and minimal background noise.

Question 2

Are there any size or resolution limits for PNG files?

Accepted Answer

Most conversions perform best when the table text is sharp and readable, typically from images around 150–300 DPI or higher. Very large PNG files may take longer to process, and very small or heavily compressed images can reduce OCR accuracy. If results look off, try uploading a higher-resolution image or cropping the PNG to only the table area.

Question 3

How is my uploaded data handled and is it secure?

Accepted Answer

Your PNG is processed to extract table text and structure, then used to generate an Excel (.xlsx) output file. Use the tool only for content you have the right to process, and avoid uploading sensitive personal or confidential data unless you are comfortable with online processing. If you need enterprise-grade workflows for extracting structured data from websites, PDFs, and images into spreadsheets, Thunderbit can help teams automate extraction and export to Excel or Google Sheets.

Question 4

Can the tool handle handwritten tables in PNG images?

Accepted Answer

Handwritten tables are supported only in limited cases, and accuracy depends heavily on handwriting clarity, consistent spacing, and clean scans. Printed or typed tables typically convert far more accurately than handwriting. If you must convert handwriting, use a high-resolution scan, keep the page flat, and ensure strong contrast between ink and background.

Question 5

What should I do if the output Excel file has errors or missing data?

Accepted Answer

First, try re-uploading a clearer image, cropping to the table region, and adjusting OCR language settings to match the document. If the table has faint lines or low contrast, increasing contrast or using a higher-resolution PNG can improve detection. For complex layouts, consider splitting one large table into multiple images and converting them separately, then combining the results in Excel.
