You'll need this online json editor https://jsoneditoronline.org (remove anything on left side if there is any code).

• open alignment.json in notepad(keep it opened)
• copy everything from there(ctrl+a, then ctrl+c)
• paste it in left area in online json editor (ctrl+v)
• copy this code
  const prefixes = ['Anub', 'Leito', 'Nibbles', 'Billyy', /* add any other prefixes for animations you want to clean from alignment.json */]
function query (data) {
  return filterKeys(data, key => {
    return !prefixes.find(pref => key.includes(pref))
  })
}
function filterKeys(obj, predicate) {
    // The function to filter keys based on the predicate
    if (Array.isArray(obj)) {
        // If it's an array, filter each element
        return obj.map(item => filterKeys(item, predicate));
    } else if (typeof obj === 'object' && obj !== null) {
        // If it's an object, filter its keys
        const result = {};
        Object.keys(obj).forEach(key => {
            if (predicate(key)) {
                // If the key matches the predicate, add it to the result
                result[key] = filterKeys(obj[key], predicate);
            }
        });
        return result;
    }
    // Return the value if it's not an object or array
    return obj;
}
