tabularix 0.4.0

High-performance framework for layout-resilient Excel table extraction

Smart, layout-resilient data extraction from Excel documents.

---

Tabularix

Tabularix is a high-performance framework designed to identify, extract, and organize "hidden data" trapped in fragmented, messy Excel files. It transforms highly variable visual spreadsheets into clean, structured formats (such as Apache Arrow tables, Pandas DataFrames, or Polars DataFrames) at native speeds.

Developed as a direct continuation of the Archery framework, it combines a blazing-fast Rust core engine with ergonomic Python scripting bindings to enable powerful "Configuration as Code" recipes.

💡 Quick Example

The Scenario

Suppose we have a spreadsheet containing a sales report table surrounded by empty rows, headers, and metadata, as shown in the layout analysis below:

Instead of hardcoding static cell coordinates (e.g., A3:E8) which break when columns or rows are added, deleted, or shifted, Tabularix uses Range Matchers to dynamically locate table boundaries relative to their visual markers.

The following example shows how to define the header and data patterns, locate the table, and export it:

import polars as pl
from tabularix import (
    extract_table_with_header_and_data,
    grid,
    group,
    load_workbook,
    non_empty,
    regex,
    value,
)

# 1. Load the workbook and get the target worksheet.
workbook = load_workbook("tests/data/sample.xlsx")
sheet = workbook.get_sheet("complex")

# 2. Define the header row pattern (starts with "Region", then 4 Quarters matching Q1-Q4 regex).
header_pattern = group(
    value("Region"),
    regex(r"^Q[1-4]$").repeat(min=4, max=4)
)

# 3. Define the data row pattern (region name, then 4 non-empty numeric quarter cells).
data_pattern = grid(
    group(
        regex(r"^(?!Total).*$"),  # Match any string except "Total" (the footer marker).
        non_empty().repeat(min=4, max=4)
    ).one_or_more()
)

# 4. Extract the structured Table with dynamic coordinate scanning.
table = extract_table_with_header_and_data(
    sheet,
    header_pattern,
    data_pattern,
    clean_names=True
)

# 5. Export zero-copy to a Polars or Pandas DataFrame.
df = pl.from_arrow(table.to_arrow())
print(df)
