Install and first workbook

Alephgrid is pre-release: the ready installation path today is building from source. Native binaries, package managers and published container images arrive with v0.1.0 — the releases page tracks exactly what is ready.

Build from source

Requires Rust 1.88+ and Node 20+.

git clone https://github.com/alephgrid/alephgrid && cd alephgrid
(cd web && npm install && npm run build)   # build the UI
cargo build --release
./target/release/alephgrid

The first build compiles DuckDB from source, which takes several minutes.

Launch

./target/release/alephgrid flights.parquet   # opens http://127.0.0.1:7878
./target/release/alephgrid --demo-rows 10000000   # or 10M generated rows

On your own machine there is no sign-in and the server listens on 127.0.0.1 only. Data lives in ./alephgrid-data (change with --data-dir).

Import a file

Drag a CSV, TSV, Parquet, JSON/JSONL or gzip file onto the window, or pass it on the command line. The import is streamed and reviewed in a side pane with column types and samples before it becomes a table. XLSX files import as editable sheets.

Write a formula

Sheets use Excel syntax: =SUM(B2:B9), =XLOOKUP(...), =Budget!B4*2. A sheet formula can read a whole table by name:

=SUMIFS(orders[amount], orders[region], A2)

That runs as one query over the whole table — not one lookup per row — however many rows the table has.

Save and export

Everything persists automatically in the workbook’s DuckDB file. Export any table or filtered view as CSV, Parquet or JSON lines, and sheets as XLSX (with a report of anything XLSX cannot hold).
