About the formats
What is CSV?
A CSV file is a table saved as plain text, one row per line with the values separated by commas. In countries where the comma is the decimal mark, such as Sweden and Germany, Excel uses semicolons instead. CSV has no formatting, formulas or multiple sheets.
What is Excel?
XLSX has been the Excel format since Office 2007. A workbook can hold many sheets, and keeps numbers, dates and formulas. ConvertOrino reads the values Excel saved for each cell, also from older XLS files and LibreOffice ODS files.
Questions
Questions and answers
Is it safe to convert my files here?
Yes. ConvertOrino converts your files with code that runs in your own browser. Nothing is uploaded to a server, nobody else can see your files, and they are gone as soon as you close the page.
My CSV uses semicolons. Does that work?
Yes. The separator is detected automatically, whether it is a comma, semicolon, tab or vertical bar.
Are leading zeros kept?
Yes. Values such as 007 or postcodes that start with 0 stay as text, so the zeros are not lost.
Is the CSV to Excel tool free?
Yes, completely free. There is no sign up, no watermark and no limit on the number of files.
Is there a file size limit?
There is no fixed limit, because your own device does the work. Very large files are limited by the memory of your device. Phones handle files of a few hundred megabytes, computers handle much more.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any modern browser, including Safari, Chrome, Edge and Firefox, on phones, tablets and computers. Nothing needs to be installed.
Does it work offline?
Yes. Once the page has loaded, the conversion works without an internet connection, which also proves that your files are not sent anywhere.
