From picture to data
A spreadsheet is useful because every value has an address. An image has none — it is a single object, and any calculation you want to do on it has to start with someone retyping the contents.
GridFiller closes that gap. It looks at the image the way a person does, identifies the header row and the column boundaries, and rebuilds the table as structured data that behaves like a normal sheet.
What you can convert
- Photos of printed reports, price lists, and menus
- Scanned forms and delivery notes
- Charts and tables exported as images from BI tools
- PDF pages that have no selectable text layer
- Screenshots of web tables and dashboards
The workflow
1. Upload
Drag in up to 20 images or PDFs, 20MB each.
2. Decide how they combine
Align by headers, append rows, or keep each source on its own named sheet.
3. Extract
GridFiller returns a structured table, usually within seconds per file.
4. Edit
Review the grid, correct any cell, and rename columns.
5. Export
Download CSV or XLSX and continue in Excel, Google Sheets, or Numbers.
Accuracy depends on the source
Sharp, high-contrast images with a visible header row give the best results. Blurred captures, skewed photos, merged cells, and columns separated only by whitespace are the situations where a value is most likely to land in the wrong place.
That is why the editable grid comes before the export rather than after it. Treat the extraction as a first draft that removes the typing, and give the numeric columns a quick read before you download.
Common questions
- Do I need to crop the image first?
- Not usually. Cropping to the table does help when the image is busy, but GridFiller looks for tabular structure on its own.
- Can I use the result in Google Sheets?
- Yes. Export CSV or XLSX and import it into Google Sheets. Direct Sheets sync is not available yet.
- What happens to my uploads?
- Files and their conversions are stored privately in your account under row-level security, and you can delete them at any time.
