# TabLib

A minimally-preprocessed dataset of 627M tables (69 TiB) extracted from HTML, PDF, CSV, TSV, Excel, and SQLite files from GitHub and Common Crawl.

This includes 867B tokens of "context metadata": each table includes provenance information and table context such as filename, text before/after, HTML metadata, etc.

A smaller 0.1% sample of this dataset can be found [here](https://huggingface.co/datasets/approximatelabs/tablib-v1-sample).

For more information, read the [paper](https://arxiv.org/abs/2310.07875) & [announcement blog](https://approximatelabs.com/blog/tablib).

# Dataset Details

## Sources
* **GitHub**: nearly all public GitHub repositories
* **Common Crawl**: the `CC-MAIN-2023-23` crawl

## Reading Tables
Tables are stored as serialized Arrow bytes in the `arrow_bytes` column. To read these, you will need to deserialize the bytes:

```python
import datasets
import pyarrow as pa

# load a single file of the dataset
ds = datasets.load_dataset(
    'approximatelabs/tablib-v1-full',
    data_files='tablib/job=github_000005/batch=000001/part=000001/manifest.parquet',
    token='...',
)

df = ds['train'].to_pandas()

tables = [pa.RecordBatchStreamReader(b).read_all() for b in df['arrow_bytes']]
```

## Licensing
This dataset is intended for research use only.
