Come convertire Excel in JSON online – guida passo dopo passo

Usa questo convertitore Excel → JSON per trasformare fogli di calcolo in array o oggetti JSON per API, database e app web.

  1. Passo 1 – Carica il file Excel

    • Carica un file .xlsx, .xlsm o .xls.
    • A sinistra appare l’anteprima del foglio selezionato.
    • Per file CSV, usa un tool CSV→JSON o converti prima in Excel.

  2. Passo 2 – Configura le opzioni

    • Seleziona il foglio da convertire (per workbook multi-foglio).
    • Abilita “La prima riga contiene intestazioni” per usare la prima riga come chiavi JSON.
    • Opzionalmente indica un intervallo (es. A1:D100) per convertire solo una parte del foglio.

  3. Passo 3 – Verifica l’output JSON

    • Con intestazioni, il JSON è un array di oggetti (uno per riga).
    • Ogni riga diventa un oggetto JSON con intestazioni come chiavi e valori di cella come valori.
    • Controlla che date, numeri e testo siano formattati correttamente.

  4. Passo 4 – Copia o scarica il JSON

    • Usa “Copia” per inviare l’array JSON negli appunti.
    • Usa “Scarica” per salvare come file .json.
    • Importa il JSON in database, invialo a API o usalo nelle app frontend.

Quick tips for Excel to JSON

  • Keep one header row at the top so each JSON object gets consistent keys.
  • Dates and numbers are read as they appear in Excel; double-check them before sending to APIs.
  • For very large sheets, convert smaller ranges first to keep output manageable.
Example: Excel spreadsheet to JSON array
// Excel spreadsheet (with headers)
| Name        | Email              | Age | Active |
|-------------|--------------------|-----|--------|
| Maeve       | [email protected] | 28  | true   |
| Alex        | [email protected]   | 32  | false  |

// JSON output
[
  {
    "Name": "Maeve",
    "Email": "[email protected]",
    "Age": 28,
    "Active": true
  },
  {
    "Name": "Alex",
    "Email": "[email protected]",
    "Age": 32,
    "Active": false
  }
]

Domande frequenti

What Excel formats are supported?

This tool supports modern Excel formats including .xlsx, .xlsm (macro-enabled), and legacy .xls files. Both single and multi-sheet workbooks are supported.

How does sheet selection work?

After importing an Excel file, you can select which sheet to convert using the dropdown in settings. Sheet names are automatically detected from your workbook.

Can I convert specific cell ranges?

Yes. Use the range option in settings to specify a cell range like 'A1:D10'. Leave it empty to convert the entire used range of the selected sheet.

How are headers handled?

When 'First row contains headers' is enabled, the first row values become JSON object keys. When disabled, generic keys like 'Column1', 'Column2' are used.

Is my data secure?

Yes, all data processing happens entirely in your browser. Your Excel file is parsed locally and never sent to any server, ensuring completely private and secure conversion.
