How to Use This Tool
This tool allows you to upload a folder containing JSON metadata files and/or a master JSON file (array of metadata objects) for NFTs, edit them individually or in batch, and download all updated files as a single ZIP containing both individual JSONs and a deduplicated master JSON with all editions.
- Load Folder: Click "Choose Folder" and select a directory containing your .json files (including a master JSON file if present). Then click "Load Folder" to parse them. Duplicates are removed based on the 'edition' field.
- Batch Updates:
- Update All Images with New CID: Enter the new IPFS folder CID (e.g., QmNewCID123). This will update the 'image' field in all metadata to use the new CID with the edition number (e.g., ipfs://newCID/1.png). It applies to all uploaded files.
- Update All Descriptions: Enter a new description and click the button to apply it to all files.
- Update All Dates: Click to set the 'date' field to the current timestamp in all files.
- Individual Edit: Select a file from the dropdown, edit the JSON in the textarea, and click "Save Changes to This File".
- Preview: Click "Generate Preview of All Updated Files" to see the current state of all metadata in text form.
- Download: Click "Download All Updated JSONs" to get a ZIP file containing all individual JSON files and a deduplicated master JSON file with all editions.
Note: Changes are applied to all loaded metadata files, including the master JSON. Duplicates are removed based on edition number. Always preview to verify before downloading.
