How to back up your captured data
Published . Updated .
Open History in the Only Fan Out side panel and click Export all as JSON: you get one file, only-fan-out-history.json, with every stored conversation, written in your browser. History keeps 100 conversations at most, so a backup is how you keep older ones.
How do you back up your captures?
- Open the side panel and choose History.
- Click Export all as JSON under the list of captured conversations.
- Keep only-fan-out-history.json from your downloads somewhere safe.
Can you load a backup back into the panel?
No. The panel has no import, so the backup is for your own records and scripts. For a spreadsheet, export the conversations you need as CSV instead, as exporting searches shows.
When are old captures removed?
When History passes 100 conversations, or about 8 MB, the oldest go first. Back up before a big research session if you want to keep what is there.
