Supported Input Files and Formats

You can attach up to 8 files per task. You can mix and match file types (for example, attaching a presentation template as a target and an Excel sheet as the data source):

Images: PNG, JPG, WEBP, GIF, BMP — screenshots, phone photos, scans, and sketches
Presentations: PPTX — slides, embedded charts, and shape-based diagrams
Documents: PDF — multi-page annual reports, whitepapers, and scientific articles
Spreadsheets: XLSX, XLS, CSV, TSV — structured tabular data sources
Plain text: direct numerical descriptions and paste buffers

Supported Chart Types

FastToChart supports the broad spectrum of professional and academic charts:

Bar and column charts (clustered, stacked, 100% normalized, horizontal)
Line graphs and multi-band area plots
Scatter plots and bubble charts with 3-variable radius sizing
Pie charts, donut charts, and polar Nightingale rose plots
Waterfall charts, EBITDA bridges, and variance diagrams
Sales and conversion funnel pipelines

Radar and spider graphs across radial spoke axes
Table heatmaps with color-coded matrix cells
Bump and rank tracking slope charts
Conceptual schematic diagrams and flowcharts (exported as editable vector figures)

Natural Language Prompting

FastToChart understands natural conversational instructions. You can direct the planner and editor just as you would talk to an analyst colleague:

'Extract the regional sales chart from page 14'
'Make this chart editable and change the color palette to calm blue'
'Update the revenue chart in my presentation using data from this Excel table'
'Convert to a line chart and show data labels'
'Remove the Total column and recalculate in percentages'

Data Verification and Confidence Scoring

Key Feature

Verification is an essential step in professional workflows. FastToChart color-codes extracted values to give full transparency:

In Practice & Details

Green cells (100% confidence): Numbers read verbatim from printed labels on the image or parsed directly from native file caches.

Important Detail

Yellow cells (75–90% confidence): Values interpolated from the axis scale based on bar height or point position. Always review these against the original.

Important Detail

Red / Null cells: Genuinely unreadable or obscured points. FastToChart leaves these empty rather than inventing false numbers.

Export Formats and Office Integration

Key Feature

PowerPoint (.pptx): Generates true OpenXML chart objects. When opened in PowerPoint, clicking 'Edit Data' launches the native Excel table. Quality is vector-sharp at any zoom level.

In Practice & Details

Excel (.xlsx) and CSV: Structured worksheets where categories populate column A and series populate adjacent columns. Numbers are clean for formulas.

Important Detail

PNG: High-resolution raster images for instant inclusion in emails or documents.

Updating Existing Presentation Templates

Key Feature

When you need to keep corporate slide masters, brand typography, and animations intact, FastToChart can update only the underlying chart values without touching slide layout or styling.

In Practice & Details

This also works for charts constructed from custom PowerPoint shapes: bar heights and labels are recalculated with proportional fidelity.

Chrome Extension
