Open My Account → Import in the web client. Imports belong exclusively to your signed-in account. The original CSV stays unchanged; passwords and raw CSV data are not saved in browser storage.
Prefer Toggl Track’s Legacy CSV export for Timekeeper imports. It preserves
source client names in a Client column, so you can map them directly to existing
Timekeeper clients or create clients under their source names, independently of
their projects.
Both Legacy and Detailed Report CSV exports are supported. The newer Detailed Report export we verified omits client names. When that column is missing, work-session imports suggest client names from projects instead; review and correct those mappings before importing.
In classic Toggl Track, select the correct source workspace, open Reports → Detailed, choose the date range. Include individual start/end dates and times and descriptions. Toggl documents CSV export as a paid-plan feature; PDF summaries and Toggl 2.0/Focus exports are different formats. See Detailed Reports and export prerequisites.
Supported headers include Member with Stop date/Stop time, and the legacy
User with End date/End time. Files must be UTF-8; a BOM, CRLF and quoted
commas/newlines are supported. Dates can be ISO YYYY-MM-DD, DD/MM/YYYY or
MM/DD/YYYY, as explicitly selected. Timekeeper calculates duration from Start
and End, preserving up to nine fractional second digits. The exported Duration
column is ignored, including missing, rounded or conflicting values. Summary-only
reports without individual timestamps are unsupported.
Europe/Oslo.
Confirm its date format. Toggl workspace columns are ignored; Timekeeper has
no workspaces and imports only into the signed-in user’s account.Local source times are converted to exact UTC instants. Explicit offsets resolve repeated DST times; ambiguous or nonexistent local times require correcting the source rather than guessing. Displayed dates use your account time zone. The import does not change that preference. Work sessions remain continuous across midnight and contribute to Track’s work-session totals per client. Activities split at the account zone’s local midnight, preserving exact elapsed time and legitimate overlaps; activity-only imports do not add to those session totals. No sessions are inferred from gaps or combined from separate CSV entries.
Files are limited to 20 MiB, 100,000 source rows and 1,000 catalog mappings. Commits use at most 100 source entries and 1,000 resulting daily activities per batch. In activity mode, an interval producing over 1,000 daily parts must be split or excluded. Cancelling before creating the job writes no import or business records.
Import history records committed progress and exact imported/reused source time. Pause after the current batch, or reload and choose Resume. Reselect the unchanged CSV, original source user, time conversion and row exclusions. The original mapping plan is retained. Jobs started before work-session labels were supported keep their original tag handling when resumed, and re-importing previously imported sessions does not overwrite their labels. If your account time zone changed, undo the partial job or start a newly reviewed import. Changed destination records also require a newly reviewed job; an existing job cannot silently adopt a different mapping or a newer destination version.
A lost reply does not mean a batch failed: the server’s job history is authoritative. Retrying the same batch returns its durable outcome. Re-imports and overlapping exports recognize previous source entries regardless of filename. The import mode is fixed for each job; deliberately importing the same source as sessions and as activities uses separate duplicate histories. Previously imported records are reused without overwriting edits. Stable source IDs whose contents changed require review. Without IDs, indistinguishable rows need an explicit decision to keep separate occurrences; existing unclaimed matches require reviewed reuse or distinct creation.
Choose Undo import in history and confirm. This stops further batches of that job and reverses all committed batches, including a partial import. Undo itself is bounded and resumable; Resume Undo continues after interruption.
An upgrade that moves old work-session titles into Summary preserves automatic Undo for otherwise untouched imported sessions. Sessions you edited still require review before deletion.
Created work sessions or activities are removed first. Newly created catalog records are removed only when unused; reused records and unrelated dependants stay. Edited records require explicit Keep or Delete after reviewing current values. Running timers and records used by another active import cannot be deleted by Undo: keep them or resolve the dependency first. Retained created records produce a partial outcome. Do not remove unrelated work to make Undo complete.
Undo follows all daily parts, including later automatic repartitioning. Once all original parts are gone, deliberately importing that source again is possible. Retained records keep duplicate protection. Download audit provides a JSON record of committed outcomes and Undo decisions. Protected server database backups preserve this history; portable work-data exports omit its private import authority. The audit retains each selected entry’s original interval, duration calculated from its Start/End, source line/ID when available, selected source descriptions/project/task/tags, import mode and imported/reused outcome. Reused source time can differ from the current duration of a record that was edited after import.
