XLS to CONF Conversion: Your Questions Answered
Why choose CONF over other formats?▼
Configuration File offers human-readable text-based configuration. It's widely used for application configuration on Unix/Linux systems, 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 CONF 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 CONF 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.
How many times can I convert XLS to CONF per day?▼
There's no daily limit for free users. Convert as many files as you need, as often as you need. PRO users get additional batch processing features.
