Cell contents: image, document, bytes
Binary fields — a BLOB in SQLite, G and P fields in FoxPro, binary columns in Parquet — often hold photos, scans and documents. In the grid such a field looks like “⟨1,036 B⟩” and there is no telling what is inside. Here a right click opens the contents: the picture, the file type and the bytes themselves.
How to look
- Open a file with a binary field — SQLite, DBF with a G or P field, or Parquet.
- Right-click the cell → “Cell contents (image, bytes)…”.
The window shows the size, the type by content, the picture (if it is one) and a hex dump. “Save as file…” writes the picture or document itself to disk, without any wrapper.
What is recognized
- Images: PNG, JPEG, GIF, BMP, WebP — with a preview and the size in pixels.
- Documents and archives: PDF, ZIP (including docx, xlsx, odt), GZIP, 7-Zip, RAR, RTF, OLE (doc, xls), TIFF, ICO — the type is named and the file can be saved.
- An image inside an OLE wrapper: FoxPro G fields put a service header before the picture. The app looks for the image within the first 64 KB and saves that.
Bytes of an ordinary cell
For an ordinary cell there is “Cell bytes…”. For DBF it shows the field’s bytes as they lie in the file: you can see the encoding, leading spaces and zeros, invisible characters — whatever makes values “look equal but not be”. For other formats it shows the cell text as UTF-8.
FAQ
Does the file go to a server?
No. The contents are decoded in your browser tab.
The image does not show — why?
The data may be truncated or damaged, or it is not an image. The type is detected by signature; without one, the window shows only the bytes.
Can I replace the picture in the field?
No, the window only reads. Save the file, fix it and put it back with the tool that owns the database.
How many bytes are shown?
The dump opens in portions: the first 4 KB at once and a “Show more” button. Saving writes the whole contents.
