Extract Data from Chart Screenshots into Excel Online

When someone sends a picture of a graph without the underlying spreadsheet, extracting numbers by hand is slow and error-prone. FastToChart converts chart images directly into clean, structured Excel worksheets and CSV files.

Structured Numerical Data Ready for Formulas

Key Feature

The exported spreadsheet is organized logically: category labels in column A, followed by one column for each series. Values are saved as pure unformatted numbers, allowing immediate summation, VLOOKUP, and pivot table modeling.

In Practice & Details

Original formatting indicators—such as percentages, currency symbols ($/€/£), and magnitude multipliers (K/M/B)—are preserved in column metadata and number formats.

Dedicated Data Confidence Sheet

In high-stakes financial and research modeling, knowing data pedigree is critical. FastToChart includes a secondary 'Confidence' worksheet inside the .xlsx file that documents the extraction certainty percentage for every single cell.

High confidence (90%+): Copied verbatim from printed labels on the graph.
Medium confidence (75-90%): Calculated from axis ticks with clear geometric anchors.
Low confidence (<75%): Interpolated from small or partially obscured bars.

Export to CSV and TSV

Need to feed data into Python pandas, R, Jupyter notebooks, or Google Sheets? FastToChart also provides instant CSV export formatted with UTF-8 encoding and clean delimiter handling.

Frequently Asked Questions

FastToChart automatically detects whether the source chart uses commas (e.g. 14,5%) or points (14.5%) and normalizes numbers cleanly into standard Excel numeric format.
