Supports linear/log10 axes aligned with the image, one series per export. Perspective-distorted or rotated charts need correction first. Estimates depend on pixel accuracy.
Prepare the input
Calibrate chart axes and capture plotted values from an image.
Paste the supported structured data or log text. The sample loads only when explicitly selected and can be undone.

Keep the useful output
Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.
CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
