Turning a WhatsApp conversation into a document someone else can check

Start with the export, not the screenshots

Screenshots are the version most people arrive with, and they are the weakest version of the same evidence, for reasons that have nothing to do with honesty.

• A run of screenshots has no way of showing that nothing was left out between image four and image five. A continuous transcript does, because the gap would be visible.
• Phone screenshots often show relative times. Yesterday and 14:05 are not much use six months later when the question is which Tuesday.
• The name at the top of a screenshot is whatever you saved that person as in your own contacts. It can say Mum, or Dave Roofing, or a nickname.
• Images are trivially croppable, and everyone in the room knows it.

The export is the same conversation, from the same phone, but complete and dated. If you have not done it yet, the steps for both phones are in how to export a WhatsApp chat. Do it Without Media first, because that version is small, then do a second export with media if photos matter.

Keep the original file, untouched

Whatever you produce as a document, keep the file WhatsApp gave you, exactly as it gave it to you. Do not open the text file, fix a typo, and save it. Do not unzip it, move things around and rezip it.

Put a copy somewhere you will not touch it, and write down two things while you still remember them: the date you did the export, and which phone you did it from. If anyone later asks where the document came from, that is the answer, and it is much better given from a note made on the day than reconstructed a year later.

If you have to work on the text, work on a copy. The original export is the thing that can be compared against your document if there is ever an argument about whether the document matches.

What a message transcript usually contains

There is no single universal format, but transcripts that get used without argument tend to have the same things in them:

• Every message in the date range, in order, with nothing skipped.
• The sender named on each message, not just on the first of a run.
• A full date and time on each message, not a relative one.
• A visible marker where a photo, voice note or file was, so a reader can see that something was sent even if the file is not reproduced.
• Continuous page numbers from the first page to the last, so a specific message can be referred to by page.
• A short note saying what the document is: which conversation, which phone, which date range, exported on what date.

That last line costs you thirty seconds and answers the first question anybody asks.

Names and numbers

WhatsApp writes whoever sent each message using the name you have saved for them. If they are not in your contacts, it writes the phone number instead. So a transcript can end up attributing half a conversation to Dave Roofing and giving no indication of which number that is.

The fix is not to edit the transcript. Leave it as exported and add the identification separately: a line at the front saying which saved name corresponds to which phone number. Then the document still matches the export byte for byte, and the reader still knows who Dave is.

It is worth checking your own entry too. Your messages are usually labelled with your own name or with You, depending on the export, and a document where one side is called You reads badly when three people are working from it.

Gaps, deletions and the things the export cannot contain

Expect the other side to look for holes, and know where yours are before they do.

• Messages deleted for everyone leave a line saying the message was deleted. That line is part of the record and should stay in.
• Disappearing messages that have already expired are not in your phone, so they are not in the export.
• View once photos and videos are never included in an export. WhatsApp says so directly.
• If you exported without media, every file is a placeholder. That is fine as long as you say so, and misleading if you do not.

None of that is a reason to avoid exporting. It is a reason to describe your document accurately rather than presenting a without-media transcript as though it were complete.

Redacting, if you have to

Long chats contain things that have nothing to do with the matter. If you take some of it out, take it out visibly. Leave the message line, mark it as redacted, and keep the timestamps either side intact so the sequence still reads continuously.

Quietly deleting lines produces a document where the times jump for no stated reason, which invites exactly the question you were trying to avoid. Black boxes are boring. Unexplained gaps are not.

And redact by covering the content, not by cropping the page. A crop changes the pagination of everything after it.

Formatting, and the fact that it varies

What a court expects of the document itself differs by country, by court and sometimes by judge. As one published example, the England and Wales judiciary's general guidance on electronic court bundles, issued in November 2021, asks for computer-generated page numbers running sequentially from page 1, an index where each entry is hyperlinked to the document, bookmarks with page numbers on significant documents, and OCR on any page of typed text that was scanned rather than created digitally.

That is one jurisdiction's written guidance, quoted because it is public and specific, not because it applies to you. Check what your own court or tribunal publishes, and if you have a solicitor, ask them what they want the document to look like before you build it. Getting told after the fact that the pagination is wrong costs a reprint at a bad moment.

Doing it by hand, free

For a short exchange, the free route is fine and takes twenty minutes. Open the exported text file, paste it into Word or Google Docs, set a readable font, insert page numbers in the footer, add a line at the front describing what the document is, and export to PDF. Nothing about that is worse than a paid version.

Where it stops being reasonable is volume. Two years of a group chat is tens of thousands of lines, and a straight paste produces an unbroken wall with no page structure and every photo sitting in a separate folder. Putting each image back beside its message, in order, is the part that turns into an evening.
