Excel to web app: when to switch, what it costs and what breaks
Seven signs you've outgrown the spreadsheet, what research says about spreadsheet errors, the options in between, and what moving to a web app really costs.
Excel to web app migration: move off spreadsheets
Your business outgrew orders_FINAL_v12.xlsx. We turn the spreadsheet into a proper web app your whole team can use safely, without changing how you work.

the research
Most business spreadsheets contain errors. Nobody knows which cells.
Field audits found errors in 88% of spreadsheets studied, and 1–2.5% of formula cells wrong. It is not careless staff; it is the tool.
When the spreadsheet starts running you
Excel is a great start. Then the business grows: two people can't edit at once, someone overwrites a formula, there are five versions on WhatsApp and nobody knows which one is right.
We turn your spreadsheet into a simple web app that keeps the way you already work. Your columns become forms, everyone works on the same live data, and every change is logged. You can still export to Excel whenever you want.
Migrations start From ₹90,000, usually 4–8 weeks, with training for your team in Hindi or English.
seven signs you have outgrown the sheet.
-
several people edit daily
And someone keeps a "master" copy that is never quite up to date.
-
orders_FINAL_v3_REAL.xlsx
Versions on WhatsApp and email, and nobody is sure which is right.
-
no edit history
Nobody can tell who changed a number, or when.
-
GST details in formulas
Rates, HSN codes and invoice numbers typed or calculated by hand.
-
WhatsApp is the backup
If the laptop dies, the business stops.
-
one person knows the formulas
When they are on leave, nothing gets done properly.
what migration really involves
the hard part is not the code.
Dirty data, rules hidden in formulas and steps nobody wrote down. We find them first, so the new app does what the sheet did, without the mistakes.
- clean and de-duplicate your data
- write down every rule hidden in formulas
- run old and new side by side
- switch only when the totals match
what you get.
-
forms, not formulas
Data goes in the right way every time, with checks on every field.

people and permissions
Everyone works on the same live data, seeing only what their role needs.
-

Every change recorded: who, what and when.
-

your options, honestly.

| cost | free or included | per user, every month | from ₹90,000 once + hosting |
| who changed what | version history only | basic | full audit log |
| limits to watch | cell limits, no permissions | row limits, delegation, lock-in | none you will hit |

good questions.
Will we lose our existing data?
No. We import your existing sheets, check the numbers with you, and only switch over once everything matches.
Can we still use Excel?
Yes. You can export any report or list to Excel whenever you need it, for your CA or your own analysis.
Will my team be able to use it?
Yes. It is designed around the sheet they already know, and we train your team in person or on video, in Hindi or English.
How much does it cost?
From ₹90,000, depending on how many sheets and workflows are involved. You get a fixed quote first.
Is Google Sheets enough?
Often, for small teams. Shared Sheets with version history solve the "which file is latest" problem. They do not give you proper permissions, validation or a reliable audit log.
How do payments work?
You pay per milestone by UPI, NEFT or card, only for work you've seen running, with a proper invoice every time. The price is fixed before we start.
