XLS to TOML: Quality Comparison
Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the TOML Config format supports it. Format-exclusive metadata fields that have no equivalent in TOML Config are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality Excel 97-2003 input produces an excellent TOML Config output. Since the target format is lossless, output quality matches your input exactly. Excel 97-2003 encodes data using mathematical algorithms that preserve every data point. TOML Config prioritizes exact data preservation. The conversion maps between these approaches intelligently.
Extracting structured data from Excel 97-2003 documents to TOML Config data format involves parsing the document content and organizing it into a structured representation. Tabular data, lists, and key-value pairs are identified and converted. This is useful for data migration, analysis, and programmatic processing of document content.
The XLS to TOML conversion applies format-appropriate algorithms to ensure maximum data fidelity. Maximum of 65,536 rows × 256 columns per worksheet

XLS to TOML FAQ
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose TOML over other formats?▼
TOML Config offers simple, unambiguous configuration with clear semantics. It's widely used for Rust/Cargo config, Python pyproject.toml and application settings, making it an excellent choice for most data needs.
Will my XLS file be deleted after conversion?▼
No. Your original XLS file is never modified or deleted. Xonvert creates a separate TOML copy — your source file remains untouched.
What document quality settings should I use?▼
Default settings are optimized for the best balance of quality and file size. Adjust only if you have specific requirements.
Does this work on my phone or tablet?▼
Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.
Can I undo a conversion?▼
Since your original XLS file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new TOML copy is created.
What if my XLS file won't convert?▼
Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.
