FAQ

Do you plan to support other file formats?

No. Tablr is focused on Parquet files only. The rationale is that other formats like CSV or JSON can be easily read with a text editor.

Do you plan to add a wasm target?

No. Tablr is designed as a desktop application for performance and security reasons.
