How to convert Xlsb to Tiff

How to Convert an Xlsb File to a Tiff Image

Sheetize provides a simple, high‑performance API that lets you turn an Excel binary workbook (.xlsb) into a high‑quality TIFF picture. This is ideal for generating printable previews, archiving spreadsheets as lossless images, or embedding workbook snapshots in documents without exposing the original data.

Why Use Sheetize for Xlsb‑to‑Tiff Conversion?

  • Full fidelity – retains cell formatting, colors, charts, and embedded images.
  • Lossless raster – TIFF preserves every pixel, making it perfect for archival and print‑ready output.
  • Fast & scalable – built on .NET, runs on Windows, macOS, and Linux without needing Office installed.
  • Customizable resolution & compression – choose DPI and compression method (LZW, Deflate, etc.).

Getting Started

Add the Sheetize.ImageConverter package to your .NET project (via NuGet) and call the ImageConverter.Process method.

Sample C# Code 

using Sheetize;

var loadOptions = new LoadOptions
{
// Path to the source Xlsb file
InputFile = @\"D:\\Reports\\AnnualReport.xlsb\"
};

var saveOptions = new ImageSaveOptions
{
// Desired output file – .tiff extension selects the TIFF format
OutputFile = @\"D:\\Images\\AnnualReport.tiff\",

// Optional: control image resolution (DPI)
HorizontalResolution = 300,
VerticalResolution = 300,

// Optional: TIFF compression (e.g., Lzw, Deflate, None)
Compression = \"Lzw\"
};

ImageConverter.Process(loadOptions, saveOptions);

The snippet loads AnnualReport.xlsb and writes AnnualReport.tiff using the specified DPI and lossless compression.

Key Options for TIFF Output

  • HorizontalResolution / VerticalResolution – define the DPI; higher values yield sharper print‑quality images.
  • Compression – choose a TIFF‑compatible algorithm (Lzw, Deflate, None) to balance file size and quality.
  • ColorDepth – optionally set bits per pixel (e.g., 24‑bit RGB or 32‑bit RGBA) for richer colour reproduction.

Best Practices

  1. Use 300 DPI or higher for documents that will be printed; 150 DPI is usually sufficient for on‑screen viewing.
  2. Select LZW compression to keep file size modest while retaining lossless quality.
  3. If the workbook contains large charts or high‑resolution images, increase DPI or colour depth to avoid pixelation.
  4. Verify the generated TIFF in an image viewer or editor (e.g., Adobe Photoshop, GIMP) before distributing it.
