Corrupt Excel and CSV Recovery: Salvaging Data from Broken Imports
Month-end, payroll, or a migration is stuck because a corrupt Excel file or malformed CSV import will not load, or worse, silently dropped rows. Every hour of manual retyping raises the risk that salvageable data is overwritten for good.
We forensically recover the maximum usable data and hand you a clean re-import path.
Sound Familiar?
These are the exact issues our clients faced before professional Excel recovery and CSV repair:
- Month-end or a CRM cutover is blocked because Excel recovery fails and the master workbook will not open cleanly
- CSV repair after a bank or ERP dump leaves half the columns shifted: broken delimiters, quoted commas, and truncated rows
- Finance discovers missing stock or payroll lines days later, after someone opened a large CSV in Excel and saved over it
- Formula errors (#REF!, #VALUE!, circular refs) cascade through linked sheets and nobody trusts the totals anymore
- Ops spends nights retyping salvageable rows by hand while payroll, stock takes, or debtor imports stay offline
Excel's worksheet grid caps at 1,048,576 rows (Microsoft). Opening a larger bank or ERP CSV and saving can silently truncate the file. SA bank exports and LibreOffice versus Excel encoding mismatches make delimiter and character damage even more common at month-end.
What Corrupt Import Fix Actually Delivers
Broken file in → forensic salvage → verified clean export → re-import unblocked. Ops and finance stay in control.
Preserve the Original
We lock the corrupt Excel or CSV as evidence and work only on forensic copies
Diagnose the Break
Encoding, delimiters, truncated rows, and formula errors mapped with row-count proof
Salvage and Rebuild
Maximum recoverable cells restored into a clean workbook or CSV your systems accept
Re-Import Ready
Verified load into accounting, CRM, or staging SQL so month-end or cutover can resume
Everything You Need for Spreadsheet Data Salvage
Forensic File Assessment
We diagnose corrupt Excel files and malformed CSV imports before rewriting anything: encoding, delimiters, truncated row counts, and formula breakage mapped against the source dump.
Maximum Data Salvage
Spreadsheet data salvage recovers every readable row and cell we can reconstruct, with a clear report of what was lost versus what is re-import ready.
Delimiter and Encoding Fixes
Broken commas, semicolons, tabs, and Windows-1252 versus UTF-8 mismatches are normalised so SA bank CSVs and ERP exports parse into the right columns again.
Truncation and Row Repair
We detect silent Excel grid cuts (past 1,048,576 rows), partial last lines, and shifted fields, then rebuild a clean file with verified row counts.
Formula and Structure Cleanup
Broken links, #REF!/#VALUE! cascades, and sheet structure issues are isolated so totals and pivots stop lying before the next close.
Clean Re-Import Path
You leave with validated Excel or CSV ready for Xero, Sage, Pastel, CRM, or SQL import, plus a short playbook so the next dump does not recreate the crisis.
Formats and Systems We Recover Into
From 18 Hours/Week to 2 Hours/Week
How a mid-market distributor unblocked month-end after a corrupt stock Excel and a bank CSV dump that truncated rows on open.
The Manual Crisis
- Finance and warehouse leads retyped salvageable lines from a half-broken workbook
- Bank CSV columns shifted after Excel auto-detected delimiters and encoding
- Roughly one in five import attempts needed a full reprocess
- Month-end close slipped by four business days while stock and cash disagreed
- Nobody knew which rows Excel had silently dropped after a large dump was saved
The Recovered Process
- Forensic Excel recovery restored 99% of blocked stock rows with a verified count
- CSV repair produced a clean UTF-8 export that Sage and the bank reconcile accepted
- Formula errors isolated so board pack totals matched the ledger again
- Re-import completed in one controlled window instead of nights of retyping
- Row-count and encoding checks added so the next dump fails loudly, not silently
Before vs After Excel Recovery and CSV Repair
How It Works
From first call to re-import ready files in days, not another stalled close.
Send the Broken Files
Share the corrupt workbook or failed CSV, what system it should load into, and what is blocked (payroll, stock take, cutover, or month-end).
Free Diagnosis Call
30-minute call with finance or ops to confirm salvage scope, urgency, and which fields must be perfect before re-import.
Recover and Verify
We run forensic Excel recovery and CSV repair on a controlled copy, prove row counts and samples, then deliver clean files for your approval.
Re-Import and Guardrails
Support the load into your target system and leave encoding, delimiter, and row-count checks so the next dump fails loudly instead of silently.
Frequently Asked Questions
What kinds of corrupt Excel and CSV problems can you fix?
We handle workbooks that will not open cleanly, formula cascades (#REF!, #VALUE!, broken links), malformed CSV imports with wrong delimiters or encodings, truncated or shifted rows, and files damaged after someone opened a large dump in Excel and saved. The goal is spreadsheet data salvage plus a clean re-import path, not a new ETL build.
Will you overwrite our only copy of the master file?
No. We work from forensic copies, document what was recovered versus unrecoverable, and only hand back clean Excel or CSV once your team has checked samples and row totals. Live systems stay untouched until you approve the re-import.
How is this different from building an Excel-to-database pipeline?
A pipeline is for recurring scheduled loads once data is already trustworthy. This engagement is emergency corrupt import fix work: unblock month-end, payroll, stock takes, or CRM cutovers when a single broken file is holding the business. We can add import guardrails afterwards if you want the next dump protected.
Why do South African bank and ERP CSVs break so often?
Local bank statement CSVs and ERP exports often mix encodings, use locale-specific delimiters, and include quoted commas inside amounts or narratives. Opening them by double-click in Excel or LibreOffice can scramble columns or truncate rows. When that file is saved back, the damage becomes permanent without a corrupt import fix from the original bytes.
How long does Excel recovery and CSV repair usually take?
Urgent single-file salvage often completes within 1 to 5 business days once we have the original dump and target schema. Multi-sheet packs with formula repair, several bank formats, and verified re-import into Xero, Sage, or a CRM typically land in 1 to 3 weeks including sign-off.
How much does professional spreadsheet data salvage cost?
Focused corrupt Excel or CSV recovery for a blocked import typically starts around R25,000. Multi-file month-end or migration salvage with verification reports and re-import support usually lands between R45,000 and R95,000. Against 8 to 12 hours a week of manual cleanup and delayed closes, most mid-market finance teams see payback inside one or two months.
Stop Losing Rows to Corrupt Excel and Bad CSVs
If a single broken workbook or bank dump is holding payroll, stock takes, or a CRM cutover, manual retyping is the most expensive and riskiest option left.
Tell us which file failed, which system it must load into, and what date the close or go-live cannot miss. We will show you how much is salvageable and how quickly a clean re-import can run.
