Do you struggle with **unusual data file formats** when advertising? Or do you make **simple edits** and don’t want to buy an expensive editor? Take advantage of the new version of the [Blending Bull](https://store.mergado.com/detail/blendingbull/#about) app, which has been enriched with functions for **editing XML and CSV feeds**.
## What is Blending Bull
- An app that helps marketing specialists or online store staff to **edit data feeds in XML, CSV**, or other text formats.
- In practice, users use it to [merge data feeds into one output file](https://www.mergado.com/blog/blending-bull-merges-feeds). It is can be processed by other apps. At the same time, Bull can **unify the format of elements** if XML files in different formats are combined.
- Now it can also **edit data feeds**. These are usually simple needs where a smarter tool is overly robust or special requirements that it does not support.
- You can also use it, for example, to **process data XML into CSV**, which are then uploaded to Mergado by a data import rule.
- More experienced users from the ranks of marketing specialists or agencies will appreciate its **versatility**. Users with less experience will certainly solve their needs either **intuitively or with the help of instructions**.

### What features Blending Bull has to offer
- **Rules for data editing**, which allow you to edit element values, create new elements, delete elements, convert XML to CSV, or vice versa.
- **Adding text to the beginning or end of the data feed** is useful for defining your closing elements in XML, or for example for adding a header to the CSV.
- **Merging multiple data sources into one output file**. For data sources, you can delete the beginnings and ends of file contents, such as when processing XML feeds.
- **Processing of one data source**. It allows you to use powerful functions for editing its content.
- Fast data processing.
- File Creation Wizard.
- Regular data updates.
Edit feeds intuitively. **Get the Blending Bull app** — it will be a powerful assistant for merging feeds and editing problematic files.
