How it works

Three steps, no account

1

Paste or drop your CSV

Comma-separated values with a header row works best. You can also upload a .csv file directly.

2

Review the table

Transpose it, delete blank rows, or remove duplicates before you generate output.

3

Pick a format and generate

Choose from 28 output formats, then copy the result or download it as a file.

FAQ

Common questions

Is my data uploaded anywhere?
No. Parsing, editing, and generating output all run in your browser using JavaScript — the CSV you paste or upload never touches a server.
How large a file can I convert?
There's no server-side limit because there's no server involved — your browser's own memory is the ceiling.
What happens if a row has the wrong number of columns?
The parser expects every row to have the same number of comma-separated values as the header row and flags "Invalid CSV format" if one doesn't — fix the mismatched row and it'll re-parse as you type.
Can I edit the data before converting?
Yes — the table below the input lets you transpose rows and columns, delete blank rows, or remove duplicate rows before you generate the final output.

How to Convert CSV to Excel Online?

Transform your CSV data into an Excel spreadsheet (XLSX or XLS) using our online converter. This is a convenient way to open and edit CSV data in Excel or other spreadsheet applications.

1. Upload or Paste Your CSV Data

Upload your CSV file or paste the CSV data into the provided input area. The converter will automatically detect the delimiter (usually a comma) used in your CSV file.

2. Choose the Excel File Format

Select the desired output format: XLSX (the newer, recommended format) or XLS (the older format).

3. (Optional) Customize Conversion Settings

Depending on the converter's capabilities, you might have additional options:

  • Sheet Name: Specify the name of the worksheet in the Excel file.
  • Data Cleaning: Some converters might offer basic data cleaning options (e.g., handling missing values).

4. Download the Excel File

Once the conversion is complete, you can download the resulting Excel file (XLSX or XLS).

What is CSV?

CSV (Comma-Separated Values) is a simple file format used to store tabular data, such as a spreadsheet or database. Each line of the file is a data record, with each field separated by commas.

What is Excel?

Microsoft Excel is a widely used spreadsheet program. It allows users to create, edit, and analyze data in tabular format. The converter transforms your CSV data into an Excel workbook that can be opened and manipulated using Excel or other compatible spreadsheet software. The two main Excel file formats are:

  • XLSX: The newer XML-based format. This is generally the preferred format.
  • XLS: The older binary format.

Note: While this describes the process, the actual implementation of an online CSV-to-Excel converter would involve server-side processing to handle file uploads and downloads and potentially using a library to create the Excel file.
