tidely 1.3.0b2

The Ultimate Data Cleaning Engine for Python

Tidely

The Operating System for Data Quality

Zero-Configuration • Explainable • Deterministic • Fast

---

Install

pip install tidely

The Magic

import tidely as td

result = td.clean("sales.csv")

clean_df = result.df

print(result.summary())

---

Why Tidely?

Real-world datasets are messy.

Missing values.

Broken dates.

Mixed datatypes.

Duplicate records.

Memory waste.

Encoding issues.

Schema drift.

Normally you spend hours writing cleaning scripts.

Tidely turns all of that into a single function call.

Explainable Cleaning

Tidely never silently changes your data.

Every transformation is documented.

Example

✓ Converted "Order Date" to datetime

Reason

Detected temporal values.

Impact

Allows time-series operations.

---

✓ Downcasted int64 → int16

Reason

Values fit inside Int16.

Impact

61% lower memory.

---

Philosophy

Tidely follows three principles.

Never silently modify data.

Every transformation is visible.

Deterministic.

Same input.

Same output.

Every time.

Local First.

Runs entirely on your machine.

No cloud.

No API keys.

No LLMs.
