products
Twelve products on four surfaces, ten of them in the stores and two in review on the Atlassian Marketplace. Among the eight JetBrains plugins, five write JSON Lines that JSONL Lens opens, and JSONL Lens, Parquet Lens and Log Lens read the same filter expression in their Pro tiers, as do the two VS Code extensions, which share one Pro key between them. The two Atlassian apps put the same paged tables on a Confluence page or a Jira issue. Each product has a page of its own, with what it opens and where its free tier ends, its newest notes and, for the ten in the stores, the price as the store shows it.
jetbrains ides
Eight plugins for IntelliJ IDEA and the other JetBrains IDEs. Each viewer is free; Pro is a subscription per plugin, with a 30-day trial that each plugin runs on its own.
JSONL Lens
JSON Lines and NDJSON files of any size, gzipped included; Pro filters the whole file and writes the matches out as JSONL, CSV or Parquet
Log Lens
multi-gigabyte plain, JSON lines, logfmt and ANSI logs with level chips and follow mode; Pro filters, follows the filter live, charts the levels and exports
Parquet Lens
Parquet, Avro, TFRecord, Arrow and Feather datasets paged off disk with a schema tab; Pro filters, sorts, profiles and writes CSV, JSONL or Parquet
SQLite Lens
read-only browser for SQLite database files, no lock taken; Pro adds a SQL console, exports, a profile report, a two-file diff and a whole-table sort
XLSX Lens
Excel workbooks streamed read-only, every sheet, merged cells and formats; Pro exports, profiles, sorts and filters every row, and diffs two workbooks
Notebook Lens
Jupyter notebooks rendered as documents with no kernel, outputs included; Pro diffs two notebooks, searches every cell and exports the source
DuckDB Lens
read-only browser for DuckDB database files, every schema in a tree; Pro adds a SQL console, exports, a two-file diff and a whole-table sort

vs code
Two of the products, JSONL Lens and Parquet Lens, exist for VS Code as well, on Open VSX and on the Visual Studio Marketplace. The viewers are free there too. Pro is a key bought once through Polar, and the same key serves both extensions; before any key is entered, Pro runs as a 14-day trial on each machine.
JSONL Lens for VS Code
JSON Lines and NDJSON files of any size as a grid, with search, a schema tab and record detail; Pro filters the whole file, exports and scans exact stats
Parquet Lens for VS Code
Parquet, Avro, TFRecord, Arrow IPC and Feather v2 files as a table, with search and a schema view; Pro filters the whole file, exports and scans exact stats
Lens Pro for VS Codeone key for both extensions, sold through Polar
confluence and jira
Lens File Viewer puts the same tables on a Confluence page or a Jira issue: an attachment opens where it sits, read with the permissions of whoever is looking at it, and never leaves Atlassian. Both editions are in review on the Atlassian Marketplace.
Lens File Viewer for Confluence
CSV, Excel, JSONL, Parquet and, in the 2.4.0 build under review, log attachments on the page, searched whole, with a schema view for Excel and Parquet
