// Test to verify the final n8n array format fix
console.log('Testing n8n array format fix - Version 1.1.8...');

console.log('\n=== Issue Analysis ===');
console.log('Persistent error: outputData.entries is not a function');
console.log('Problem: n8n expects specific array nesting structure');

console.log('\n=== Format Comparison ===');

console.log('\n--- Working Grouped Output Format ---');
const workingFormat = [[{
  json: {
    files: [{ sheets: { Sheet1: { data: [...] } } }],
    totalFiles: 1,
    processedAt: "2025-01-04T12:00:00.000Z"
  }
}]];
console.log('return [[{json: {...}}]];  // Array of arrays');

console.log('\n--- Previous Broken Format (v1.1.7) ---');
const brokenFormat = [
  { json: { fileName: "file.xlsx", rows: [...] } },
  { json: { fileName: "file.xlsx", rows: [...] } }
];
console.log('return separateItems;  // Direct array - BROKEN');

console.log('\n--- Fixed Format (v1.1.8) ---');
const fixedFormat = [[
  { json: { fileName: "file.xlsx", sheetName: "Sheet1", rows: [...] } },
  { json: { fileName: "file.xlsx", sheetName: "Sheet2", rows: [...] } }
]];
console.log('return [separateItems];  // Array containing array - FIXED');

console.log('\n=== Key Insight ===');
console.log('n8n expects: [array_of_items] not array_of_items');
console.log('Both modes must return the same structure:');
console.log('- Grouped: [[single_item_with_all_data]]');
console.log('- Separate: [[item1, item2, item3, ...]]');

console.log('\n=== Final Code Change ===');
console.log('Before: return separateItems;');
console.log('After:  return [separateItems];');
console.log('Result: Matches working grouped output structure exactly');

console.log('\n=== Expected Behavior ===');
console.log('✅ No more "outputData.entries is not a function" error');
console.log('✅ Each sheet becomes separate workflow item');
console.log('✅ Proper n8n workflow execution');
console.log('✅ Compatible with n8n v1.113.3');

console.log('\n=== Version 1.1.8 Ready ===');
console.log('This should be the final fix for the n8n compatibility issue.');
