Converter JSON → XLSX
Upload JSON and get XLSX online. Simple files work immediately, while advanced structure changes, value transformations, export filters and scheduled automation can be configured in your account after signup.
Need transformations, not just format conversion?
Sign up when you need to change values in cells, resize and convert images, or filter exports to include only selected items.
What is a JSON to XLSX converter
A JSON to XLSX converter takes data from a JSON file or API response and builds a modern Excel XLSX file. This is useful when the source works in JSON but the next system needs data for reports, price lists, manager handoffs and table integrations. In a simple case, JSON keys become columns, cells or output nodes, and the products array becomes product rows. In production workflows, the output schema matters: which fields are exported, how nested objects are handled, what happens to image arrays, how columns are named and which records are excluded by filters.
When you need a converter
When data is already in JSON, but the next step needs a table, Excel file, feed or another structured format for import.
What the converter does
It reads JSON, selects repeated records, turns keys into output fields and helps save the structure for repeat exports.
Why setup matters
The same JSON can be exported in different ways: flat table, multiple sheets, feed or filtered file with renamed fields.
JSON to XLSX example
The quick converter builds a simple XLSX table from JSON. For production exports, sheets, columns and nested-data rules matter, so precise XLSX structure is configured in a profile after signup.
Before
source JSON{
"products": [
{
"sku": "SKU-001",
"name": "iPhone 15",
"price": 999,
"stock": 12,
"category": "Smartphones",
"images": ["front.jpg", "back.jpg"]
},
{
"sku": "SKU-002",
"name": "Samsung S24",
"price": 899,
"stock": 8,
"category": "Smartphones",
"images": ["s24.jpg"]
}
]
}After
XLSX structure| Category | Images | Name | Price | SKU | Stock |
|---|---|---|---|---|---|
| Smartphones | ["front.jpg","back.jpg"] | iPhone 15 | 999 | SKU-001 | 12 |
| Smartphones | ["s24.jpg"] | Samsung S24 | 899 | SKU-002 | 8 |
A profile can create one products sheet or split data into multiple sheets: products, images and stock separately.
After signup and profile setup
XLSX structure| SKU | Name | Price | Stock | Category | Image URLs |
|---|---|---|---|---|---|
| SKU-001 | iPhone 15 | 999 | 12 | Smartphones | https://example.com/front.jpg | https://example.com/back.jpg |
| SKU-002 | Samsung S24 | 899 | 8 | Smartphones | https://example.com/s24.jpg |
When you need a JSON to XLSX converter
This conversion is usually part of regular catalog, price-list, stock and supplier-data preparation, not just a one-off file.
Supplier catalogs
JSON from a supplier API can be mapped to the structure needed for catalog, prices, stock and images.
Price lists
Prices, currencies, discounts and stock can be prepared for later import or delivery.
CMS and ERP
Data can be adapted to the format expected by a website, CMS, ERP, PIM or internal system.
Marketplaces and channels
Catalog data can be prepared for channel requirements where required fields and stable ids matter.
Analytics and checks
Managers can review assortment, prices and stock in a clear table or feed structure.
Recurring exports
A profile can run repeatedly and deliver the result by email, FTP/SFTP, webhook or another channel.
Common JSON to XLSX conversion mistakes
Most problems come from JSON structure: nesting, arrays, value types and fields that do not match the receiver.
Repeated node not selected
If JSON contains products, offers or items, define which array becomes output rows.
Lost nesting
arrays inside JSON need a rule: merge into one cell, split into columns or move to a separate sheet
Different fields per product
If some records miss a field, decide whether to keep it empty, fill a default value or exclude the record.
Value types not normalized
Prices, dates, true/false and empty values should be normalized before export.
Unneeded records exported
Filters help export only active products, required categories, stock records or selected suppliers.
No result check
Before scheduling, check preview, required fields, encoding and several test records.
JSON to XLSX online or manual conversion
A one-time check and a production export need different approaches. Compare the options before setting up the process.
| Method | Pros | Cons |
|---|---|---|
| Manual code | Maximum flexibility for unique schemas. | Requires a developer, tests and maintenance. |
| Local script | Fast for a repeat technical task. | Harder to manage files, logs, permissions, schedules and delivery. |
| Eofferix | Preview, profiles, rules, files up to 2 GB and scheduled runs. | Complex structures need a saved profile. |
Limits, safety and production workflows
Eofferix helps check JSON structure and prepare output without changing the source file. For recurring catalogs, large files and exact rules, use a saved profile.
Up to 5 MB without signup
Good for quick checks of simple JSON files.
Up to 2 GB after signup
Large catalogs and recurring files are processed with saved rules.
Source stays unchanged
Eofferix creates a separate result.
Structure control
If keys or nesting change, update only affected rules.
Value transformations
Cleanup, normalization, prices, filters and fields.
Result delivery
Email, FTP/SFTP, webhook and other channels.
Other JSON conversions
Eofferix can also help with other formats for catalogs, price lists and supplier exports.

What the JSON to XLSX converter supports
What the JSON to XLSX converter supports
Small JSON files can be checked directly on the page, while production rules are saved in a profile.
Nested objects and arrays
Eofferix helps turn nested data into a clear output structure: columns, sheets, nodes or feed fields.
Field mapping
Rename fields, choose order, skip unnecessary values and prepare the file for the receiving system.
Export filters
