Converter Frequently Asked Questions
How do I convert only specific data from my Excel file?
Our converter includes a built-in search and selection feature. Once you upload your file, simply search for the data you want or manually check the rows you need. When you select an export format, our tool will only convert your selected data.
I have a large Excel file with many rows and columns. How do I convert only specific data?
You can use our search and filter tools to quickly find the specific data you want to convert. For example, if you have a 10,000-row sales report but only need the data for a specific region, simply search for that region's name and select those rows before converting. Also, uncheck the columns you don't need in the column visibility toggle. This way, you can extract just the relevant information without having to convert the entire file.
Is it safe to convert sensitive business files here?
Yes, it is much safer than cloud-based converters. Traditional converters require you to upload your file to their server, which can leave a copy behind. This tool uses Local Browser Conversion—your file never leaves your computer, and the data is wiped the moment you close the tab.
I have large data, I want to use it in my app/software, how is it possible?
You are in the right place. You can convert your Excel file to JSON format, which is widely used for data interchange in web applications. After uploading your file, select the JSON export option. This will give you a structured JSON file that you can easily integrate into your app or software.
Can I convert .XLS (Legacy) to .CSV?
Absolutely. We support both modern .xlsx (XML-based) and legacy .xls (Excel 97-2003) formats. You can convert either format into modern JSON, CSV, or PDF instantly.
