Palette-Based Output

PAL stores image data with a defined color palette — your XLSX renders into a format for palette-mapped imaging systems.

Quick Processing

Cloud conversion produces the PAL file rapidly. No specialized software needed on your device.

Data Privacy

Your XLSX is erased after processing. PAL outputs are purged within 24 hours from servers.

About formats

XLSX is the default spreadsheet format for Microsoft Excel since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and adopted as ISO/IEC 29500. An XLSX file is a ZIP archive containing XML documents that describe workbook structure, sheet data, styles, shared strings, formulas, charts, pivot tables, and relationships between components. Each worksheet is stored as a separate XML part where cells are organized by row and column references with typed values and style indices. The XML foundation enables programmatic spreadsheet creation and manipulation using libraries like openpyxl (Python), Apache POI (Java), and ClosedXML (.NET) without requiring Excel. XLSX dramatically expanded capacity compared to XLS: over 1 million rows and 16,384 columns per sheet, enabling use cases previously impossible in the binary format. One advantage is openness and cross-platform support — the documented OOXML specification enables implementation by LibreOffice Calc, Google Sheets, Apple Numbers, and numerous specialized tools. Built-in ZIP compression is another practical strength: XLSX files are typically 50-75% smaller than equivalent XLS files, and the modular XML structure improves data recovery when files are partially corrupted. The format supports modern Excel features including structured tables, slicers, sparklines, Power Query connections, and real-time co-authoring. XLSX has become the standard format for spreadsheet data interchange across business, scientific, and government domains.

PAL is a 16-bit per pixel interleaved YUV image format that stores color information using a luminance-chrominance model rather than direct RGB values. Each pixel pair is packed into four bytes using the UYVY byte ordering — U (Cb), Y0, V (Cr), Y1 — where two adjacent pixels share a single set of chroma (color difference) samples while each retaining its own luminance (brightness) value. This 4:2:2 chroma subsampling halves the color resolution horizontally with negligible perceptual impact, since human vision is far more sensitive to brightness variations than color detail. The format traces its conceptual roots to analog broadcast television standards developed during the 1960s and 1970s, where separating luminance and chrominance enabled backward-compatible color transmission alongside existing monochrome signals. In digital imaging, 16-bit YUV serves as a common intermediate representation for video capture hardware, frame grabbers, and image processing pipelines that work in the YCbCr color space internally before converting to RGB for display. One advantage is bandwidth efficiency: at 16 bits per pixel, UYVY requires roughly two-thirds the data of uncompressed 24-bit RGB while preserving virtually identical perceived quality, making it well suited for high-throughput video capture and real-time image processing applications. The format's direct correspondence to how video hardware captures and outputs data provides another practical benefit — many capture cards and camera sensors natively produce UYVY data, so storing it in PAL form avoids an unnecessary color space conversion step that would add latency and introduce rounding artifacts.

Frequently Asked Questions

Why convert XLSX to PAL?

PAL is a palette-based image format — useful when specific imaging systems require color palette data from your spreadsheet.

What reads PAL files?

ImageMagick and graphics tools that support palette-mapped image formats can process PAL files for viewing and conversion.

Is PAL a standard format?

PAL is a niche format used in certain graphics workflows. For broad compatibility, PNG or JPG are preferred alternatives.

Is this free?

Basic XLSX to PAL conversion is free. Premium plans extend limits for specialized graphics workflows.

Can I convert on any platform?

Yes — Convertio runs in any browser on any OS without installation or sign-up.

Is my data safe?

Uploaded files are deleted after conversion. PAL outputs are removed within 24 hours.
