spectraview is a simple tool for viewing and analyzing vibrational spectroscopy data. It shows graphs of data from different file types. You can see clear lines, zoom in, and check specific points with ease. The tool supports many file formats used in chemistry and science, like JCAMP-DX, CSV, JSON, and SPC files.
It uses both Canvas and SVG for smooth drawing and good performance. The tool includes smart ways to reduce data points without losing important details. This lets you handle big data sets without slowing down your computer. spectraview also makes it easier to spot peaks and correct baselines in your spectra.
This tool works on Windows and needs no programming knowledge to use.

Use your mouse to zoom into areas of interest by scrolling.
-
Move the cursor over the graph to see exact data point values.
-
Use the toolbar options for baseline correction, peak detection, and data smoothing if needed.
- File Support: Open JCAMP-DX, CSV, JSON, and SPC data files directly.
- Data Display: View data with clear lines using Canvas and SVG hybrid rendering.
- Data Handling: Large data sets are downsampled automatically for smooth display.
- Interactive Graphs: Zoom, pan, and snap crosshairs to data points for precise readings.
- Data Processing: Built-in options for baseline correction and peak detection help analyze spectra.
- Easy Controls: Toolbar buttons let you apply data filters and save your work.
- Export: Save modified or raw data as CSV or JSON for later use.
- Use the mouse wheel or trackpad to zoom in or out on your data graph.
- Click and drag to move around the graph view.
- Move your mouse over graphs to see crosshair lines.
- The crosshairs snap to the nearest data point for exact values.
- Click the Baseline Correction button in the toolbar.
- Choose the method and threshold to remove unwanted baseline drift.
- Click Apply to update the graph.

- Adjust sensitivity to find important peaks.
- Detected peaks will be marked on the graph.
spectraview supports common spectroscopy data files:
- JCAMP-DX: Widely used in infrared and Raman spectroscopy.
- CSV: Simple numerical data in comma-separated values format.
- JSON: Structured data format for flexible importing.
- SPC: Proprietary spectroscopy file format.
Files can be loaded directly from your PC.
- Program does not open: Restart your PC and try again.
- Cannot open file: Check the file format is supported and the file is not corrupted.
- Errors during installation: Make sure you have permission to install new programs on your PC.
- Graph does not show: Verify you opened a data file and not an unsupported format.
- Performance feels slow: Close other programs and try again. Large files may take longer to load.
- Save your sessions often using the Save option in the File menu.
- Use the exported CSV or JSON files to share data or use in other programs.
- Check the View menu to customize how graphs and data tables look.
- Use the Undo button to reverse recent changes.
