CSV Cleanroom

Local-first CSV cleanup workspace for partner feeds, reusable rules, and exportable review artifacts.

UseKit Home

Start with Quick Clean for fast cleanup, then switch to Recipe Studio for advanced authoring.

What this tool does

CSV Cleanroom validates and normalizes CSV files locally, then exports the cleaned file together with review artifacts you can keep, share internally, or reuse on the next delivery.

      Best for

      Not for

      Input

      Load a CSV, pick a starter template or recipe, then review inferred schema, issue groups, mappings, and cell-level changes in one workspace.

      Output

      The export package can include cleaned.csv, issues.json, report.html, rejects.csv, recipe.snapshot.json, and manifest.json.

      How to use

      1. Load CSV input and a starter template or saved recipe.
      2. Analyze the file, accept safe suggestions, then review issue and mapping panels.
      3. Apply fixes, verify the report preview, and export the package your importer or reviewer actually needs.

      Privacy / local processing

      Core parsing and cleanup workflows run in-browser. Raw CSV data is not persisted unless you explicitly save local history or recipe artifacts.

      Limits / tradeoffs

      Reusable recipes make repeated imports faster, but they only help when the incoming feed shape is known. Very large CSVs still depend on available browser memory, and importer-specific business rules still need a human owner.

      FAQ

      Can I reuse cleanup rules?

      Yes. Recipe Studio supports reusable rule sets for repeated datasets.

      What outputs are available?

      You can export cleaned CSV, issues JSON, report HTML, rejects CSV, recipe snapshot, and manifest, depending on what the run produced.

      Does this tool require account login?

      No. CSV Cleanroom can be used without account signup.

      Which files are usually kept after review?

      Most teams keep cleaned.csv for import, issues.json for audit detail, and report.html for human review.
