Excel out, CSV the importer accepts
Upload one workbook or several and get plain CSV back — UTF-8, comma separated, values rather than formatting. Every sheet becomes its own file, so nothing is left behind just because it wasn't the tab you had open.

Your download link Stays live for 60 minutes. Save the files as soon as they're ready — after that the link expires and the files are removed.
Why not Save As → CSV?
Because it saves the sheet you happen to be looking at, quietly leaves the others behind, and picks an encoding based on where your laptop thinks it is.
Every sheet, not just the open one
A workbook with twelve tabs gives you twelve CSVs, each named after its sheet. Nothing disappears because it wasn't the tab in front.
UTF-8, every time
Accented names and non-Latin text survive the trip. Not a locale lottery, and not something you find out about when the import is rejected.
Company data stays yours
Nothing kept, read or used to train anything. Files go when the 60-minute link expires. Worth knowing, since most files converted here are customer or payroll data.

One workbook, one sheet, an English-language laptop: Save As does the job for nothing, and you should use it. The trouble starts at volume — a dozen files before an import window closes, each needing open, Save As, confirm the warning, close without saving. Or the file comes back rejected because the accented names arrived as question marks, or because half the data was on a tab nobody thought to check. Uploading a folder in a browser sidesteps all three, on any machine, with or without Excel.
What a CSV can carry, and what it can't
A CSV holds values and nothing else — no colours, no column widths, no charts, no formulas. That is the point of it, and usually why the system on the other end asked for one. What matters is which values it holds, and how they are written.

Every sheet becomes a file
⧉A CSV holds one table, so a workbook with tabs can't be one file — but it shouldn't be one tab either. Each sheet comes out as book-Customers.csv, book-Stock.csv and so on, named after the tab. A single-sheet workbook just keeps its own name.
The value, not the formatting
ΣA cell holding 1240.5 comes out as 1240.5, whether it's displayed as €1,240.50 or rounded to 1241. Exporting what the cell shows would put a currency symbol and a thousands comma into your data — and quietly round the half away.
UTF-8, pinned
éNot whatever the converting machine's locale happened to be. Müller stays Müller, and so does anything that isn't Latin at all.
Commas and quotes escaped properly
"A value like Smith, Ltd comes out in quotes, and a quote inside a value is doubled — which is exactly how CSV is defined. Anything reading the file properly puts it back in one cell.
Formulas arrive as their answers
fxA CSV can't hold a formula, and an importer wants the result rather than the calculation. Keep the workbook as your editable copy and treat the CSV as the thing you hand over.
What a CSV genuinely cannot keep
Colours, fonts, column widths, charts, merged cells, comments and the formulas themselves. None of that is a limitation of this tool — a CSV is a text file with commas in it, and every one of those things is why the receiving system asked you not to send a workbook. If the importer is fussy about column order or headers, arrange that in Excel before converting rather than editing the text afterwards.

Who asks for a CSV
Usually a machine, and machines don't negotiate about file formats.
R
Databases & scripts
A bulk load, a Python job or a colleague's pipeline wants plain text — nobody parses XLSX for fun.
P
Mailing & ad platforms
Contact lists and audience uploads are CSV everywhere, and reject anything with formatting in it.
F
Webshop catalogues
Product feeds go up as CSV. The prices are maintained in a spreadsheet. Something has to bridge the two.
T
Long-term storage
Plain text opens in thirty years' time. A proprietary workbook format is a promise nobody made.
S
Stripping a file down
Going through CSV drops the formatting, the hidden columns and the decade of accumulated cruft.
Whatever it's for, upload the workbooks and download the CSVs.
Need something slightly different?
Going the other way? CSV to Excel Cyborg. Want one workbook per tab rather than one CSV per tab? Split Excel Cyborg. Sending it to someone who shouldn't edit it? Excel to PDF Cyborg — all included in one account.
Common questions
Getting started
What is Excel to CSV Cyborg?
A web app that converts Excel workbooks into plain CSV files. Upload one or several, get UTF-8 CSVs back with the same names. Nothing to install, no ads.
Which files can I upload?
XLSX and older XLS workbooks, one at a time or up to 50 together. You don't need Excel on the machine you're using.
Why would I need a CSV at all?
Because something asked for one — an import screen, a database load, a mailing platform, a developer. CSV is the plain-text lowest common denominator that every system can read.
What survives the conversion
What if my workbook has several sheets?
Every sheet becomes its own CSV, named after the tab: book-Customers.csv, book-Stock.csv and so on. A CSV holds one table, so a workbook with tabs can't be a single file — but nothing is dropped because it wasn't the sheet you had open. A one-sheet workbook simply keeps its own name.
What happens to my formulas?
They become the values they currently show. A CSV can't hold a formula, and an importer wants the answer rather than the calculation — keep the workbook as your editable copy.
And my colours, charts and column widths?
Gone, deliberately. CSV is values only. That's the point of it, and usually why the system on the other end asked for one.
What about numbers that are formatted?
You get the value, not the formatting. A cell holding 1240.5 comes out as 1240.5 whether Excel displays it as €1,240.50 or rounds it to 1241 on screen. Exporting what the cell shows would put a currency symbol and a thousands comma into your data and quietly lose the half — which an importer would either reject or read wrong.
Are commas inside my text a problem?
No — a value like "Smith, Ltd" comes out in quotes, and a quote inside a value is doubled. That is exactly how CSV is defined, and anything reading the file properly will put it back in one cell.
What encoding do I get?
UTF-8, always, so accented and non-Latin characters come through intact. If you then double-click the CSV and Excel shows nonsense, that's Excel guessing — the file is fine, and importing it rather than opening it will prove that.
How big can the files be?
Up to 50 workbooks, 200 MB each. A large one simply takes longer — four workbooks including a three-sheet one convert in about four seconds.
Price and privacy
How much does it cost?
A €1 day pass gives you 24 hours of unlimited conversions. Yearly (€6) and lifetime (€30) plans are also available, and every plan unlocks all 79 AppsCyborg tools.
When does the download link expire?
After 60 minutes. Save the files as soon as they're ready — after that the link expires and you'd upload the workbooks again.
What happens to my data?
Your workbook is used to make the CSV and then deleted along with it when the 60-minute link expires. Nothing is kept, read, indexed or used to train anything, and requests are anonymous — no ads, no trackers. Worth knowing, since most files converted here are customer or payroll data.
Can I use the result commercially?
Yes. The data is yours; the CSV made from it is yours to sell, send or publish. No attribution needed.
Still have a question?
We usually reply within a day.
CSV the importer accepts, in about a minute.
