I had a huge, problematic file to convert that couldn't go through the usual automated conversion process. The Zamzar team responded quickly to my request for help, and they took the extra steps needed to do it manually.

It’s my first time using it. I had some complications doing it. I’m not very good at this. But I wrote to the company and I had a lot of help. I’m satisfied with customer service and with the app.

I use Zamar whenever I need to convert audio and video files from multiple submitters to 1 uniform file format for Audio and Video Editing. I can do multiple large files in a short amount of time.

Christopher Bee

Great for when you need a lot of conversions in a short time. You have directly access and can even put the subscription on for just a month.

Sabina Calis

Great thanks to you all for helping me to get the OLD files converted correctly. 20 years, quite a long time, reviewing the files brings much memory to me. That's the best gift I received last year. Thank you all again.

I feel like Zamzar is an active team member, especially for projects that I work on where I am the workhorse and it saves so much time and frustration. I am spoiled with Zamzar, because they have set the bar for file conversion and customer service very high.

Fantastic service! My mom's computer died and she has 1000+ Word Perfect files she wants to keep for some reason. Since Word Perfect is basically dead, I decided to convert all her files. Zamzar's converter was perfect.

CSV Document Format

CSV Converter

CSV, sometimes known as a comma separated values file is commonly used by spreadsheet applications. It allows plain text data to be saved in tabular format.

If a user has a large volume of data and needs to transfer it between applications then a CSV file is often used. The CSV file uses the comma character to separate the data (although other characters can and are used). Structurally a CSV file is fairly simple. It is this simplicity which makes them so powerful and popular because you can easily export and import data into other programs such as Microsoft Excel or the Notepad application.

Many applications have an import wizard that a user can follow which then enables the data to be displayed in an organised and clear way.

XLS Document Format

XLS Converter

The XLS format, also known as the Excel Binary File Format, is the format for spreadsheet files created by Microsoft or other spreadsheet programs. XLS files contain one or more worksheets that are made up of cells that are arranged by row and by column, and they allow users to do calculations by inserting formulas into cells. XLS files also support charts, images, pivot tables and more, and this means that they are often the format of choice for anyone doing any form of calculation or working with numerical data. This file format also allows users to create and record macros using a macro-programming language called Visual Basic.

XLS files are widely used in education and in work, although in 2007 they were replaced by the XLSX file format as the primary file type used for Excel spreadsheets.

Users can open XLS files with either Office for Windows or Office for Mac, and both these programs support features, including macros that have been written in Visual Basic. While applications like OpenOffice allow XLS files to be opened, some features may be limited. XLS files can also be opened on Android or iOS.
