Create CSV File

PreviousUpload FolderNextVerify & Bulk Upload

Last updated 5 months ago

To successfully perform a Bulk Upload in Buildtree, you need a correctly formatted CSV file that pairs with your .

This CSV file provides essential metadata for each asset, such as titles, descriptions, attributes, and more. Follow this guide to create your CSV file properly and ensure a smooth upload process.

Steps to Create a CSV File

  1. Use Our CSV Template Buildtree provides you with a sample CSV template for the collection metadata. So, you just need to fill the file with your project information. This template includes all the necessary fields, such as:

    • Token ID

    • Name

    • Description

    • Attributes

  • Green: Mandatory

  • Orange: Optional

You need to replace the dummy text on the document with your project information. Each row represents an asset in your . The TokenID column should match the file names in your asset folder exactly.

Find here the Example Template 📂

  1. Fill Out the Metadata

  • Name: Provide a name for each asset.

  • Description: Add a brief description for each asset.

  • Attributes: If your project includes attributes, fill them out in the designated columns (e.g., Color, Rarity, etc.). These attributes will define specific traits or properties for each asset.

Example:

tokenId
name
description
color
rarity

0

Golden Horizon

A stunning sunset shot

Gold

Rare

1

Midnight Dreamer

A serene night scene

Blue

Common

  1. Requirements for the CSV File

    • Do not apply styles, colors, or additional formatting to the CSV.

    • Ensure all columns are correctly labeled and completed—empty fields will not be added.

    • Save the file as a CSV (.csv) format only.

    • The "TokenId", "Name" and "Description" columns are mandatory. Not having them in your CSV file can cause an error.

    • Token Name must be less than 100 characters.

    • Each token description must be less than 500 characters.

    • Each Attribute & Value name must be less than 100 characters.

    • Values from each Attribute must range from 0 to 50 units

Important Notes

  • Any errors in the CSV may result in upload failures or incorrect asset data. Review your file carefully before uploading.

  • If you previously uploaded assets or attributes, performing a bulk upload will replace them with the new data from your CSV file.
