Key highlights of the appRead log, CSV, Excel, JSONL and Parquet attachments at a glance on the issue, no download. Files never leave Atlassian
Log attachments with level chips
The log in this shot is 38 MB and it opened in about three seconds. Chips filter to one level in a click, and the footer keeps the full count: 14,326 ERROR and 28,652 WARN in this file.
A 120,000-row workbook opens in seconds
A 120,000-row Excel workbook attached to the issue opens in seconds: headers detected, date and number formats applied, every sheet listed in the schema view.
CSV, JSONL and Parquet as paged tables
The panel lists every data file on the issue; CSV, JSONL and Parquet open as paged tables, and Parquet gets a schema tab with types and column statistics.
More details
Someone attaches a 38 MB log to a Jira issue; the next person downloads it to read one line. Lens File Viewer opens it on the issue: the panel lists the issue's data attachments as paged tables.
CSV, Excel, JSONL, Parquet, logs and text open; logs and JSONL open gzipped too. Logs show level chips, a next-error arrow and a hit count. Tables export to CSV. The app runs on Atlassian. Your browser keeps a few things: the theme, the ids of attachments you open and the text of your searches (up to 200 of each), the notices shown to you and your review answer.
Every site starts with a 30-day evaluation. Free up to ten users; past ten, every user is billed through the Atlassian Marketplace: USD 3.35 per user per month up to 100 users, less per user on larger sites. An unbought evaluation ends at a license screen; attachments keep their download links.

Version information
Version 2.18.0•for Jira Cloud
- Release date
- Oct 11th 2026
- Summary
- Find waits for a loading file; a band letter read whole; a date as shown
- Details
Find now waits for a CSV or JSON Lines attachment to finish loading. The lit rows are then the hits, and the count covers the whole file rather than the part already read. On a .csv.gz or .jsonl.gz attachment, a search typed during decompression runs when the file opens instead of being dropped.
On a UTF-8 log with a Windows-1250 band, Find read one byte of an accented letter through the page, so Váci út 12 was listed for st and the count of s ran past the lines. The letter is whole to Find now. In a workbook under a Hungarian locale, a date typed the way the grid shows it, 2023. 10. 02., is now found; the search used to see only 10/2/2023.
