About formats

XLS is the binary spreadsheet format of Microsoft Excel, first introduced with Excel 1.0 for Macintosh in September 1985 and becoming the dominant spreadsheet format worldwide. The format stores workbooks as OLE2 compound document files using the Binary Interchange File Format (BIFF), organizing sheets, cells, formulas, formatting, charts, pivot tables, macros, and metadata across multiple internal streams. Each cell record encodes the cell's value (number, string, boolean, error, or formula), position, and formatting index, while shared string tables and style records reduce redundancy. The format evolved through BIFF versions (BIFF2 through BIFF8), with BIFF8 (Excel 97) establishing the structure used through Excel 2003. XLS supports up to 65,536 rows and 256 columns per sheet, a limit that drove the creation of XLSX. One advantage is universal spreadsheet compatibility — XLS files are recognized by every major spreadsheet application including LibreOffice Calc, Google Sheets, Apple Numbers, and dozens of programming libraries across all platforms. The format's mature feature set is another strength: XLS handles complex formulas, conditional formatting, data validation, named ranges, array formulas, external references, and VBA macros. Although XLSX replaced XLS as the default in Office 2007, the binary format persists in financial institutions, legacy reporting systems, and any environment where Excel 97-2003 compatibility is required.
Developer: Microsoft
Initial release: September 1985
JP2 (JPEG 2000 Part 1) is an image format based on the JPEG 2000 compression standard, developed by the Joint Photographic Experts Group and published as ISO/IEC 15444-1 in December 2000 as the successor to the original JPEG standard. Unlike JPEG's block-based discrete cosine transform, JPEG 2000 uses discrete wavelet transform (DWT) compression, which eliminates the characteristic 8x8 block artifacts visible in highly compressed JPEG images and instead produces a smooth, gradual quality degradation. The format supports both lossy and lossless compression within the same codestream, along with features absent from original JPEG: 16-bit and higher bit-depth images, arbitrary numbers of color channels, alpha transparency, region-of-interest coding (allocating more bits to important areas), and progressive quality or resolution refinement from a single compressed stream. One advantage is superior image quality at low bit rates — JPEG 2000 produces visibly cleaner images than JPEG at equivalent file sizes, particularly below 0.5 bits per pixel where JPEG exhibits severe blocking. The progressive decoding capability is another strength: a single JP2 file can be decoded at any resolution or quality level without encoding multiple versions, valuable for remote sensing and medical imaging where the same image must serve both thumbnail browsing and full-resolution analysis. JP2 is the mandated format for digital cinema (DCI), the preferred format in geospatial data (GeoJP2), and widely adopted in cultural heritage digitization.

Frequently Asked Questions

Why convert XLS to JP2?

JP2 (JPEG 2000) offers superior compression and sharper images than classic JPEG — ideal for high-fidelity spreadsheet snapshots.

What opens JP2 files?

IrfanView, Adobe Photoshop, GIMP, macOS Preview, and several browser plugins display JP2 images. Safari supports it natively.

Is JP2 better than JPEG?

JP2 produces sharper images at the same file size. However, JPEG has wider browser support, so choose based on your audience.

Is XLS to JP2 free?

Yes — convertio.tools handles XLS to JP2 at no cost. Premium plans provide batch conversion and higher resolution output.

Does it work on all devices?

The conversion itself is browser-based and works everywhere. JP2 viewing requires a compatible application on the receiving end.
