Turn any CSV file into a clean JSON array of objects. All you need is a header row – the tool automatically maps each column to a property name and creates one object per data row. 100% client‑side, so your data never leaves your computer.
Currently the tool expects comma‑separated values. If your data uses a different delimiter, save the file as a comma‑separated CSV first. A delimiter selector may be added later.
Yes, the tool preserves the original text, including leading/trailing spaces and special characters.
Up to about 50 MB of data should be handled smoothly in modern browsers. Larger files may slow down the tab; we recommend splitting the file with our CSV splitter first.
