Frequently Asked Questions
Everything you need to know about using our CSV to JSON tool effectively
What is CSV?
CSV stands for Comma Separated Values. It's a simple file format used to store tabular data, such as a spreadsheet or database. Files in the CSV format can be imported to and exported from programs that store data in tables, such as Microsoft Excel or OpenOffice Calc.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. It is widely used for transmitting data in web applications.
Is my data secure?
Yes, absolutely. The conversion happens entirely in your browser using JavaScript. Your data is never sent to our servers, ensuring complete privacy and security.
Can I convert large CSV files?
Yes, our tool can handle large CSV files. However, since the processing is done in your browser, extremely large files (hundreds of megabytes) might slow down your device temporarily.
Does it handle special characters?
Yes, our converter supports UTF-8 encoding, so it can correctly handle special characters, accents, and symbols from various languages.
