Takeout Check · Free Windows prototype

Your photos.
Their dates.
A clearer picture.

Exported Google Photos and found a folder full of JSON files? Check which photo dates can be matched, which are missing, and where the data conflicts.

Free · Version 0.1 · Windows x64 · Python source · Checksums

Read-only. This prototype checks filename/date matches. It does not fix dates or change your originals.

A look before
you make changes.

Exact matches are separated from cases that need a closer look. Ambiguous filenames and conflicting timestamps remain unresolved; upload time is never silently used as capture time.

01 / EXTRACT

Choose your export folder

Extract your downloaded archives yourself, then select the folder. Keep originals. ZIP archives and linked directories are skipped and reported.

02 / CHECK

Review date matches

The tool scans supported media filenames and JSON photo timestamps. Matches in a different directory are flagged for manual review.

03 / EXPORT

Keep the full report

Save outside the source folder. HTML, CSV and JSON include all rows; the desktop preview shows the first 500.

A small first release

Know what
the result means.

  • No EXIF reading, date repair, renaming, deletion or photo copying.
  • A missing sidecar does not mean a photo is damaged; it may already contain the correct date.
  • Dates are UTC. The tool does not recover local timezone or prove the true capture date.
  • The report cannot certify export completeness. Do not delete a cloud library based on it.
  • Synthetic tests have been run. Independent real-export trials and large-library performance are still pending.

Before your first scan.

How do I run the Windows download?

Extract the whole ZIP. Keep the EXE beside its _internal folder, then open LaunchTraceTakeoutCheck.exe. The binary is unsigned. Review the source if needed; do not bypass security warnings automatically. Choose an extracted export directory, scan, and save reports elsewhere.

What happens to my photos?

The audit opens JSON sidecars for reading and lists media filenames. It does not upload files, read image bytes or change originals. Reports contain filenames and dates; share them deliberately. The application has no account or telemetry.

Are there free alternatives?

Yes. Existing open-source Takeout tools and ExifTool can help with metadata. This free prototype is being tested for a useful preview workflow; we have not demonstrated an advantage over them or validated demand for a paid product.

Is the sample a real customer export?

No. It uses synthetic placeholder files to demonstrate matched, missing, ambiguous and conflicting rows. It is not a client case study.
