#### written in typescript using preact





![img](./example.png)

## implemented

- CSV parsing

 - comma and newline delimiter

 - quote escaping of comma for cell values

 - converts to indexeddb store

   - fast querying

   - pagination

   - renders quickly

   - persistence across browser sessions

## mvp-todo

- mark column as key, unique, exclude

- key formula (ex: `a.trim().toLower()==b.trim().toLower()` ) 

- cell transform formula (ex: `v.trim().toLower()`)

- merge modes:

  - union (include only rows where keys match comparison across sheets)

  - exclusion (include only keys with no match comparison across sheets)

  - union-keep (union + keep unmatched key rows)

- export and download serialized CSV

- export preview that live regenerates when options changed
