AI-assisted data cleaning for CSV & Excel

Clean your spreadsheet data with a plan you approve

Upload a CSV or Excel file, see a clear profile of what is inside, and review an AI-generated cleaning plan rule by rule. Nothing runs until you confirm.

100% Deterministic ExecutionOriginal file stays intact

AI generates the plan - you review every rule before execution. Your original file is never overwritten.

How it works

From messy file to reproducible result

A single guided flow takes you from upload to export, with a checkpoint before anything changes.

  1. 01

    Upload a file

    Drop in a CSV or XLSX file up to 20 MB and 200,000 rows. XLSX files process one selected sheet per project.

  2. 02

    Get a data profile

    A deterministic profiler summarizes columns, types, missing values and duplicates - before any AI is involved.

  3. 03

    Review the cleaning plan

    AI proposes structured rules with rationale, risk level and estimated impact. Edit, accept or skip each one.

  4. 04

    Confirm, run and export

    After your confirmation a deterministic engine applies the rules and produces the selected cleaned file, a PDF report and a JSON audit.

One plan, two review views

Choose your view after the plan is ready

Create one structured plan, then switch between a full list and a focused step-by-step review without changing the saved plan type.

Fast & Direct
Review all
See the complete list of suggested rules, then filter, edit and confirm in one pass.
  • A compact view of the entire plan
  • Toggle and edit supported rules in place
  • High-risk rules still need explicit confirmation
Step-by-Step
Step by step
Walk through detected issues one by one - accept, adjust or skip each suggestion before the final summary.
  • Best for unfamiliar or sensitive data
  • One issue at a time, with context and examples
  • Finish with a combined plan you confirm

These are two client-side views of the same plan. Neither view executes anything; every plan waits for confirmation, and high-risk rules ask again.

Core capabilities

Built for careful data work

Deterministic analysis and a controlled rule set keep every change explainable.

Deterministic profiling

Row counts, column types, missing values, duplicates and outlier candidates are computed by code, not guessed by a model.

Explore capability→

Controlled rule set

Cleaning happens through a fixed set of reviewable operations - no free-form code from the AI.

Explore capability→

Risk-aware review

Each real rule shows its affected columns, rationale, risk and available impact estimate. Risky rules are clearly flagged.

Explore capability→

Originals stay untouched

Runs write new output files. The file you uploaded is never modified or overwritten.

Explore capability→

Reproducible runs

Every run keeps its rule snapshot, input/output hashes and engine version for later verification.

Explore capability→

Focused run exports

Download the cleaned format selected for the run, a PDF report and a JSON audit. Planned recipe and dictionary exports stay marked as coming soon.

Your data, handled carefully

Privacy-minded by design

The product is built to see as little of your data as possible while still being useful.

Private storage

Files are stored in a private bucket and downloaded through short-lived signed links.

Minimal AI input

The AI receives statistics by default. Masked samples are optional, off by default and limited to five rows - never your full file.

Retention you control

Your files stay available until you delete their project or your account.

Transparent processing

Reports record exactly which rules ran and what changed, so results can be audited.

      FAQ

      Common questions

      CSV and XLSX files up to 20 MB and 200,000 rows. For XLSX you choose one sheet per project.

      No. The AI only proposes structured rules. A deterministic engine applies them after you confirm, and your original file is never overwritten.

      Trimming whitespace, normalizing casing and missing-value tokens, replacing values with an explicit mapping, parsing numbers and dates, casting types, renaming columns, dropping empty rows/columns and exact duplicates, and flagging outliers.

      Each run stores a frozen rule snapshot, file hashes and the engine version, and provides PDF and JSON audit downloads. Cross-project recipe reuse is still coming soon.

      No. You review and adjust rules through controlled options, then download the cleaned file and audit artifacts after the run.

      The public beta remains free while our Creem live account is under review. Paid pricing is shown transparently, and checkout will open only after live approval and final billing verification.
