How do I import data?
You can paste JSON text directly into the input area or use the "Import CSV" button to load data from a CSV file. The editor supports drag-and-drop for files as well.
What is the "Master Table" mode?
The Master Table mode allows you to flatten complex JSON structures into a CSV format for easier editing in spreadsheet software. When importing back, the system reconstructs the original JSON hierarchy.
Is my data safe?
Yes, all processing happens locally in your browser. No data is sent to any server. However, please be careful when clearing data or overwriting files.
What does the "Format" button do?
The Format button beautifies your JSON, fixing indentation and making it readable. It also validates the syntax to ensure there are no errors.
