How to convert Json to Tiff

How to Convert a Json File to a Tiff Image

Sheetize provides a high‑performance API that transforms a JSON (.json) data file into a TIFF (Tagged Image File Format) raster image. This is perfect for generating loss‑less printable graphics, reports, or thumbnails from structured data without exposing the original JSON content.

Why Use Sheetize for Json‑to‑Tiff Conversion?

  • Lossless raster – TIFF stores every pixel without compression artifacts, making it ideal for archival and print‑ready outputs.
  • Rich color depth – supports 8‑, 16‑, and 32‑bit per channel images, so you can retain high‑fidelity visualizations.
  • Cross‑platform – runs on Windows, macOS, and Linux without requiring a browser or Office installation.
  • Customizable DPI & compression – control resolution for screen vs. print and choose LZW or Deflate compression to keep file sizes reasonable.

Getting Started

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

Sample C# Code 

using Sheetize;

var loadOptions = new LoadOptions
{
// Path to the source JSON file
InputFile = @"C:\\Data\\SurveyResults.json"
};

var saveOptions = new ImageSaveOptions
{
// .tiff extension selects the TIFF format
OutputFile = @"C:\\Images\\SurveyResults.tiff"

// Optional: set rendering DPI (default is 96)
HorizontalResolution = 300,
VerticalResolution = 300,
};

ImageConverter.Process(loadOptions, saveOptions);

The snippet reads SurveyResults.json, renders it (e.g., as a chart or table), and writes SurveyResults.tiff using 300 DPI and LZW compression for a high‑quality print asset.

Key Options for TIFF Output

  • HorizontalResolution / VerticalResolution – define the reference DPI; higher values give sharper print results.
  • Compression – Lzw (lossless, widely supported), Deflate (lossless, better compression), or None (uncompressed).
  • BackgroundColor – fill the canvas background; TIFF does not support true transparency, so a solid color is required when the source visualisation includes alpha.
  • ColorDepth – choose 8, 16, or 32 bits per channel to match the desired quality and file size.
  • PageWidth / PageHeight – set the logical size of the output image (in inches or millimeters) when converting vector‑based visualisations.

Best Practices

  1. Use 300 DPI or higher for print‑ready TIFFs; 72‑150 DPI is sufficient for on‑screen previews.
  2. Select LZW compression to keep file size down while remaining lossless.
  3. Specify a solid background color if your JSON visualisation contains transparent elements – otherwise the transparent regions will appear black.
  4. Validate the TIFF by opening it in an image viewer or editor (e.g., Photoshop, GIMP) to ensure colors, resolution, and compression meet expectations.
  5. Pre‑process JSON – ensure the data is tidy and that any charting or tabular rendering logic used by Sheetize receives a consistent schema.

By following these steps, you can reliably convert any JSON dataset into a high‑quality TIFF image suitable for archival storage, publishing, or inclusion in professional documents.
