Product Feed CSV to Excel for Easy Editing

Opening a feed CSV straight in Excel can change SKUs and prices. Converting it to .xlsx keeps the values as they are.

Open the CSV to Excel converter and drop the feed. Turn on type detection for prices and stock, but keep SKUs and barcodes as text so 000123 stays 000123.

Excel gets a real .xlsx file with a bold, frozen header row. A sheet holds at most 1,048,576 rows, so check the row count first.

Edit, sort and filter in Excel, then export back to CSV for the importer. Check the headers against the importer rules before you upload.

Everything runs in your browser and nothing is uploaded.

Frequently asked questions

How do I convert CSV to Excel?

Drop your CSV file (or paste the data), check the options, click Convert and download the Excel result.

How big can a file be?

It depends on your device. A few hundred MB usually works.

Which conversions does the Format Converter support?

Any direction between JSON, CSV, Parquet and Excel (.xlsx), for one file or a whole folder. Nested JSON is flattened into columns such as address.city. For Excel, the first sheet is read; old .xls files are not supported.

Why did my number or date change after converting?

Types are detected from the values. Turn off "Detect types" to keep everything as text, which also keeps leading zeros in IDs and phone numbers.

Tip: Do not double-click a feed CSV. Convert it so Excel does not reformat the SKUs.
