How to Import

Drag and Drop

Drag one or more log files directly onto the LogPeak window. The import wizard opens automatically.

File Picker

  1. Click the Import button on the Welcome screen or from the menu
  2. Select one or more files from the file picker
  3. LogPeak validates and previews the data
  4. Click Import to load the data

Multiple Files

You can import multiple files at once. This is useful for:

  • Date-split logs — e.g., app-2026-04-01.jsonl, app-2026-04-02.jsonl
  • Rotated log files — Multiple files from the same source

LogPeak merges them into a single unified view, so you can search across all files at once.

Import Progress

During import, LogPeak shows:

  • Progress bar with percentage
  • Number of rows processed
  • Estimated time remaining

Append to Existing

You can also append new files to an already-open log view. This lets you add more data without starting a new session.
