Convert CSV to Excel online

Add file

Input file

Our API accepts one or multiple .CSV files as input. The .CSV files must comply with our CSV specification.

Max file size for web uploads: 50 GB

Output file

The API will return a ZIP archive of .XLSX files, one for each input file. Since Excel has a limit of about one million rows, it could be that the rows are divided into several files.

Conversion methods

Using our Java tool

Download the RebaseData client Java tool . To convert your database using RebaseData, run the following command: 

                    java -jar client-0.0.5.jar convert --output-format=xlsx file.csv output-dir/
Using CURL

Replace file.csv with the path to the file you want to convert.
The file output.zip will contain a Excel file, one for each input file. If something went wrong, output.zip contains the error message. 

curl -F 'files[]=@file.csv' 'https://www.rebasedata.com/api/v1/convert?outputFormat=xlsx&errorResponse=zip' -o output.zip

How long does it take?

The conversion process takes between 15 seconds and multiple minutes. It depends on the size of the database.
