Core features

Built for how agents actually read data

Spreadsheet formulas and 2D spatial layouts confuse language models. Siglata gives agents SQL execution and relational tables.

sql_execution/transformNative SQL

SELECT c.region, SUM(o.amount) AS total_arr FROM orders o JOIN customers c ON o.customer_id = c.id GROUP BY c.region;

SQL instead of cell formulas

Language models write typed SQL cleanly. They struggle with nested VLOOKUPs, coordinate offsets, and brittle formula syntax. Siglata lets agents run SQL queries directly on workbooks.

schema/relationsTyped Tables

TABLE orders (id UUID PRIMARY KEY, customer_id UUID, amount DECIMAL, status VARCHAR);

Tables instead of spatial grids

Humans rely on visual proximity, blank spacer rows, and merged headers. Agents need explicit structure. Siglata stores data as relational tables with foreign keys.

Vectorized query execution at database speed

Siglata executes analytical queries directly against columnar vectors. Multi-table joins, window functions, and aggregations run in single-digit milliseconds with zero memory bloat.

50M+ rows/sVectorized analytical scan throughput on compressed columnar data.

< 1msMedian query latency on multi-table relational joins and group-by aggregations.
