User Guide: JSON to Excel Extension

This extension is made by mydataprovider.com. It helps you turn JSON data into an Excel file in a few clicks.

What this extension does

• Reads your JSON file.
• Finds data fields and records.
• Creates an Excel file (.xlsx).
• Lets you download the result.

Before you start

• Make sure your file ends with .json.
• Use a complete file (not cut, not broken).
• If possible, keep file names simple (for example: orders_2026.json).
• Close very heavy browser tabs if your computer is slow.

Step-by-step instructions

1. Open the extension page.
   Open your browser and start the extension.
2. Choose your JSON file.
   Click the upload/select button and pick your file from your computer.
3. Wait for loading.
   The extension reads your data. Large files can take more time.
4. Check preview (if shown).
   Look at sample rows. Confirm that columns and values look right.
5. Click Convert.
   The extension prepares your Excel output.
6. Download the Excel file.
   Click Download and save the .xlsx file to your folder.
7. Open in Excel.
   Open the file and quickly check headers, rows, and numbers.

Simple example

If your JSON has a list of orders (name, date, amount), the Excel file will usually show:

• One row per order.
• One column per field (Name, Date, Amount, and more).

Tips for better results

• Use clear JSON structure when possible.
• Keep the same field names across records.
• If data is very large, split it into smaller files.
• After export, check date and number format in Excel.

Common problems and quick fixes

1) File does not upload

• Check file extension: it must be .json.
• Open the file in a text editor and confirm it is not empty.
• Try a different JSON file to test.

2) Convert button does not work

• Wait a little longer after upload.
• Reload the extension page and try again.
• Close and open the browser if needed.

3) Excel file looks wrong

• Check whether your JSON has nested objects or mixed data types.
• Confirm all records use similar field names.
• Try export again with a smaller sample file first.

4) File is too big / browser is slow

• Split one very large file into smaller parts.
• Close other heavy programs.
• Try again and wait until processing is finished.

Privacy note

Use files you are allowed to use. Do not share private data with other people if your company rules do not allow it.
