📊Data Tools
Data tools for the reshape-and-clean work that sits between exporting from one system and importing into another: CSV to JSON for an API that wants structured input, JSON to CSV for an analyst who wants to open it in Excel, XML to CSV for legacy enterprise exports, CSV merging when a vendor splits the export by month, and Excel conversion for systems that only accept .xlsx. Everything runs in your browser, so files you process here are not uploaded to a server, which matters when the data contains anything you would rather not share. The common misconception is that CSV is a single, well-defined format; in practice every system disagrees about quoting, escaping, line endings, header presence, and how to encode embedded commas, which is why the converters here detect quoting style and offer overrides rather than assuming. If you are new to the category, start with the CSV to JSON Converter when you need structured data for an API, the Data Merge Tool when you have a folder of similar exports that need to be combined, and the CSV to Excel Converter when the destination is a spreadsheet rather than another tool. The XML to CSV Converter handles deeply nested input by flattening on a configurable path. None of these tools change your source file; they generate clean output and leave you to handle the originals.
