# Extend rich metadata

You can extend the metadata of your digital collection as much as you want, using the tool you will find inside the "Upload to IPFS" tab. Below is a screenshot where you can find it:

This tool allows you to download your current metadata generated so far in a CSV (Comma Separated Values) format. A CSV file is a plain text file that stores data by delimiting data entries with commas.\
\
For example, for the DEMO backup, the CSV will have a first line which is: **name, description, trait\[Background]  ,trait\[Body]  ,trait\[Dress]  ,trait\[Face]  ,trait\[Hair]**

The following lines contain the information for each token with the corresponding metadata.

You can bulk edit and update the whole file more easily and quickly.

It also allows you to extend the metadata of your collection by adding these new columns:

* **youtube\_url: include the youtube\_url column in your CSV and link it to a YouTube video (ex, <https://www.youtube.com/watch?v=Mintpad>) to be displayed when someone enters to view the token.**
* **Extend attributes (traits): You can add extra information for each token, and the marketplaces will show it, especially if it has any extra information.** To add these attributes, we need to create new columns in the CSV with the following format: **trait\[NAME]\[TYPE]**. The available types are:
  * **number**
  * **boost\_percentage**
  * **boost\_number**
  * **Date: You can indicate a date, for example, the age of a token. For this, you would have the column trait\[Birthday]\[date]. Pass in a UNIX** timestamp (seconds) as the value.

You offer an example of a CSV edited using several of these extensions using the DEMO collection.[ You can download it here](https://app.nfts2me.com/examples/extend-metadata-nfts2me.csv).
