What Wrangell Data is
Wrangell Data is a no-code tool in the browser for transforming and cleaning data. Its standalone tools are free, and processing takes place on the user's computer. The site supports Excel (XLSX), CSV, and JSON files. For CSV-to-JSON work, upload a CSV or XLSX file, choose columns, preview the output, and download it. The Missing Data tool generates a report and allows filtering before preview and download. Data Merger combines two spreadsheets using a chosen column from each, while CSV Splitter divides spreadsheets into smaller sections by row or column. These tools can support work such as combining customer sales or support information and preparing data for reporting or machine learning. The maker says data stays in the browser during the merge tutorial workflow, and its example workflow does not require an account. Wrangell also offers a one-time Starter Data Transformation Package for $300, paid once, covering up to 5 input files and 10,000 rows per file. Its deliverables include conversion, cleaning, duplicate removal, a cleaning log, and a mapped process; delivery is stated as within 5 business days after files are provided, with possible clarification delays.
