What is Zedda

Zedda profiles, cleans, and validates datasets from a single Python call. Its core is written in C++17 and streams data in constant memory, so it scales from a 900-row CSV to a terabyte-scale Parquet file without changing how you use it.

Installation

pip install zedda                          # CSV only — zero native deps
pip install "zedda[parquet]"               # adds Parquet/Arrow/Feather support
pip install "zedda[clean]"                 # adds fuzzy typo detection
pip install "zedda[ai]"                    # adds AI Q&A (zd.ask with Groq/OpenAI)
pip install "zedda[parquet,clean,ai]"      # everything together

Platform support:

Platform	Base install	[parquet] extra
Linux x86_64 (glibc / musl)	✅ prebuilt wheel	✅ prebuilt pyarrow wheel
Linux ARM64 (aarch64)	✅ prebuilt wheel	✅ prebuilt pyarrow wheel
macOS Intel (x86_64)	✅ prebuilt wheel	✅ prebuilt pyarrow wheel
macOS Apple Silicon (ARM64)	✅ prebuilt wheel	✅ prebuilt pyarrow wheel
Windows x86_64	✅ prebuilt wheel	✅ prebuilt pyarrow wheel
Windows ARM64	✅ prebuilt wheel	⚠️ pyarrow has no win_arm64 wheel — Parquet requires manual build

conda users: Zedda is not yet on conda-forge. Install via pip inside your conda environment:

How to use

import zedda as zd

zd.profile("data.csv")                    # full EDA report in terminal
zd.scan("data.csv")                       # silent scan for CI/CD pipelines
zd.compare("train.csv", "test.csv")       # train/test drift detection
zd.fix("data.csv", apply=True)            # generate or apply pandas fix code
zd.ask("data.csv", "any nulls here?")     # plain-English dataset Q&A
zd.ml_ready("data.csv")                   # readiness score for ML training
zd.warnings("data.csv")                   # list all issues ranked by severity
zd.clean("data.csv", output="clean.csv")  # safe, backed-up auto-clean
zd.merge(["jan.csv", "feb.csv"], "out")   # safely combine multiple files
zd.report("data.csv", output="rep.html")  # export full report to offline HTML

Every function also accepts a pandas DataFrame directly — a file path is never required.

import pandas as pd
df = pd.read_csv("data.csv")
zd.profile(df)
