Excel help for homes & small businesses

Excel spreadsheet rescue — when the workbook your business runs on breaks

Plenty of Dorset businesses run on one giant spreadsheet built years ago by someone who has since left. When it won’t open, throws #REF! errors everywhere or takes five minutes to load, work stops. We’ve supported Microsoft Office since 1995 — and taught Excel for more than ten years at our own Dorset Microsoft Education Resource Centre — so we rescue spreadsheets calmly, honestly and usually remotely, from £20. Rated 4.9 on Google.

The problem

The spreadsheet someone built years ago

It started as a simple price list. Ten years later it runs the quoting, the stock, the wages calculation and half the filing system — and the person who built it left in 2019. Nobody dares touch it, there’s no documentation, and this morning it either won’t open, opens with errors, or has slowed to a crawl.

We see this every week. It’s nothing to be embarrassed about — a spreadsheet that grew with the business is a sign the business grew. It just needs someone who has been working with Excel since the mid-nineties to untangle it without breaking what still works.

That’s us. 365 Techies is a family-run Bournemouth firm that has supported Microsoft Office since 1995 and taught it for more than ten years at our own Dorset Microsoft Education Resource Centre. We don’t just repair the file — we explain, in plain English, what went wrong and how to stop it happening again.

What we fix

The five spreadsheet disasters we rescue most

Every rescue starts with a diagnosis, but almost all of them fall into one of these:

  • “The file won’t open” or Excel reports it as corrupt. Sometimes Excel’s built-in Open and Repair sorts it (see the free steps below). When that fails — which is exactly when most people find us — we work through deeper extraction options to pull your data and formulas out of the damaged file.
  • #REF! carnage. Someone deleted a few rows, a column or a whole sheet, and now formulas across the workbook show #REF! instead of numbers. We trace what the broken references pointed at and rebuild them.
  • Formulas overtyped with values. A well-meaning colleague typed this month’s figures straight over the calculations. If the file lives on OneDrive or SharePoint, version history can often wind it back; if not, we rebuild the logic from an older copy or from the workbook’s own structure.
  • The 90MB monster that takes five minutes to open. Slow Excel is nearly always bloat: whole-column references, volatile formulas recalculating constantly, thousands of rows of invisible “used range”, and layers of stale conditional formatting. We slim the workbook down so it opens in seconds — without changing your numbers.
  • Multi-user chaos. Conflict copies, “locked for editing” messages and a folder full of Report-final-FINAL-v7.xlsx. Usually the file is simply stored in the wrong place for teamwork — we set up proper Microsoft 365 co-authoring so everyone works in one live copy. If you’re seeing “we couldn’t merge the changes”, start with our guide to Excel and OneDrive sync conflicts.

Free fixes first

Try this before you pay anyone — including us

Fair’s fair: some rescues are free and take two minutes. Try these first.

  • Make a copy of the broken file now. Before anything else. Every repair attempt should happen on a copy, never the only original.
  • Open and Repair. In Excel choose File, then Open, then Browse to the file — but instead of double-clicking it, click it once, then click the small arrow next to the Open button and choose Open and Repair. Excel will offer to repair the workbook, or to extract just the data if repair fails. This is Microsoft’s own built-in tool and it genuinely works on mild corruption.
  • Check version history. If the file is stored on OneDrive or SharePoint, right-click it and choose Version history — you can open and restore an earlier copy from before the damage.
  • Look for the recovered copy. If Excel crashed mid-edit, reopen Excel and check the Document Recovery pane on the left for an autosaved version.

When to stop: if Open and Repair fails, if the extracted data is missing sheets or formulas, or if the workbook is behaving strangely rather than refusing to open — stop saving, stop “having a go”, and call us. Repeated failed repair attempts on the original file can make things worse, and a £20 remote look is cheaper than a rebuilt spreadsheet.

How it works

Remote-first, with free collection when hands-on is needed

Almost every spreadsheet rescue happens over a secure remote session while you watch, from £20. We always phone you before we connect — you’ll never see your mouse moving without knowing exactly who’s on the other end — and you see everything we do to your file as we do it.

If the problem turns out to be the computer rather than the spreadsheet — a failing drive, for instance — we collect the machine from you free of charge locally, sort it, and bring it back. We’re not a walk-in shop, so there’s no counter to queue at; if you’d rather talk something through face to face, we meet by appointment at Kinson Community Centre.

Bigger jobs — a full workbook rebuild, untangling years of accumulated formulas, or moving a team onto proper co-authoring — get a diagnosis first and a plain quote before any work starts. No hourly meter quietly running.

Not in Dorset? Remote rescue works anywhere in the UK — the session looks exactly the same from Bournemouth or Berwick. See how our remote support sessions work.

Why us

The firm that taught Excel, not just Googled it

Search “Excel help UK” and you’ll find gig-economy listings, one-person helplines and repair-software adverts. Here’s what we offer instead:

  • Supporting Microsoft Office since 1995. We were fixing spreadsheets when they arrived on floppy disks.
  • We taught this for over ten years at our own Dorset Microsoft Education Resource Centre. Teaching Excel means we can explain the fix, not just perform it.
  • Family-run, same faces every time. The person who rescues your workbook this month is the person who answers when you call back next year.
  • 4.9 on Google from Dorset homes and businesses.
  • Call-before-connect. Nobody remotes into your machine without speaking to you first.

Spreadsheet rescue often uncovers a wider Microsoft 365 question — which plan you’re actually on, where files should live, whether anything is backed up. Our Microsoft 365 support hub and honest guide to whether you need Microsoft 365 backup cover the follow-on questions we hear most.

Pricing & honesty

What it costs — and what we won’t promise

Straight numbers, because vague pricing helps nobody:

The honest-scope bit: no one can guarantee 100% recovery from a corrupt workbook — anyone who promises that is selling software, not a service. What we promise instead is speed and honesty: we’ll tell you quickly what’s recoverable, what it will cost, and — on the rare occasion the data really is gone — we’ll say so plainly rather than charge you to find out slowly. Then we’ll help you set things up so it can’t happen twice.

// GOOD QUESTIONS

Frequently asked

Can you fix a corrupt Excel file that won’t open?

Very often, yes. We start with Microsoft’s built-in Open and Repair (worth trying yourself first — steps are on this page), then move to deeper extraction methods if that fails. We can’t guarantee every file — nobody honestly can — but we’ll tell you quickly whether yours is recoverable before you spend real money.

How much does a spreadsheet rescue cost?

Remote rescue starts from £20, and most single-file problems are dealt with in one remote session. Bigger jobs — full rebuilds, de-bloating a huge workbook, setting up team co-authoring — are diagnosed first and quoted plainly before any work starts. We’re not VAT registered, so the price you’re quoted is the price.

Do I have to bring my computer to you?

No — and we’re not a walk-in shop, so please don’t set off with it! Nearly all spreadsheet work happens over a secure remote session while you watch, and we always phone before we connect. If the machine itself needs hands-on work, we collect it free of charge locally. Prefer to meet? We see customers by appointment at Kinson Community Centre.

Someone typed values over our formulas — can you get the formulas back?

If the file lives on OneDrive or SharePoint, version history usually lets us restore a copy from before the damage. If it’s a purely local file, we look for earlier copies and backups, and where none exist we rebuild the formulas from the workbook’s own logic. It’s slower but very often possible.

Why has our Excel workbook become so slow?

Almost always accumulated bloat: whole-column references, volatile formulas that recalculate constantly, a “used range” stretching thousands of empty rows, and layers of stale conditional formatting. We slim the workbook down without changing your figures — files that took minutes to open typically open in seconds afterwards.

Can several people work in the same spreadsheet without conflict copies everywhere?

Yes — but only if the file is stored on OneDrive or SharePoint as part of Microsoft 365, which enables real co-authoring. Files on ordinary shared drives will keep producing locks and duplicate copies. We set this up properly as part of managed Microsoft 365 at £4.85 per user per month, and our Excel and OneDrive sync conflicts guide explains the errors you’ve probably been seeing.

Do you run Excel training courses?

Not as a current product, no — though we taught Microsoft Office for more than ten years at our own Dorset Microsoft Education Resource Centre. What we do instead is explain every fix as we make it, so you and your team understand the workbook better after the rescue than before it.

Is our business data safe with you?

We’re a family-run Dorset firm — the same faces every time, supporting Microsoft software since 1995. Remote sessions happen while you watch, we always call before we connect, and your file never goes anywhere you haven’t agreed to. If you’d like the wider picture, see our guide to securing your Microsoft 365 account.

We’re not in Bournemouth — can you still help?

Yes. Spreadsheet rescue is remote-first, so it works anywhere in the UK from £20 — the session is identical whether you’re in Poole or Preston. Free collection for hands-on hardware work applies locally in the Bournemouth and wider Dorset area.

Spreadsheet down and work stopped?
