Why These Tools

Data rarely arrives in the format the next program wants. An API answers in JSON, the finance team works in a spreadsheet, the deploy pipeline reads YAML and the config file is TOML. Converting by hand means retyping, and retyping is where commas end up in the wrong column. These tools move data between formats without losing the parts that make the conversion awkward.

JSON to CSV Converter — Flatten & Export opens the category. It flattens nested objects into dot-named columns, keeps a comma inside a note from splitting the row, and finds the records inside a whole API response on its own. Text to Markdown Table Converter appears here from Table & Spreadsheet Tools because it does the next step, turning CSV into a Markdown or HTML table for documentation. YAML, TOML and type-definition generators come next.
